I'm trying to build gentoo-sources-4.0.3, but it doesn't compile. When it dies, I see a failure to compile some module. But when I look in the log, I don't see any mention of that at all. Instead, I see an internal compiler error. What? So the problems are: - The compiler is crashing, which means nobody has tried compiling this configuration of 4.0.3 with gcc 4.8.4. - A build failure is occurring that is not being recorded in the log file. - The kernel contains code that doesn't compile. Here's what prints to the screen: * ERROR: Failed to compile the "modules" target... * * -- Grepping log... -- * * CC [M] drivers/net/ethernet/chelsio/cxgb3/aq100x.o * CC [M] drivers/net/fddi/defxx.o * CC [M] net/llc/llc_output.o * LD [M] drivers/net/ethernet/chelsio/cxgb3/cxgb3.o *drivers/net/fddi/defxx.c: In function ‘dfx_pci_register’: *drivers/net/fddi/defxx.c:583:10: warning: ‘bar_len’ may be used uninitialized in this function [-Wmaybe-uninitialized] * region = request_mem_region(bar_start[0], bar_len[0], * ^ *drivers/net/fddi/defxx.c:537:18: note: ‘bar_len’ was declared here * resource_size_t bar_len[3]; /* resource length */ * ^ *drivers/net/fddi/defxx.c:583:10: warning: ‘bar_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] *-- * resource_size_t bar_start[3]; /* pointers to ports */ * ^ * CC [M] drivers/net/ethernet/dlink/dl2k.o * CC [M] net/ipv6/exthdrs.o *drivers/net/fddi/defxx.c: In function ‘dfx_pci_unregister’: *drivers/net/fddi/defxx.c:3720:5: warning: ‘*((void *)&bar_start+16)’ may be used uninitialized in this function [-Wmaybe-uninitialized] *-- * resource_size_t bar_start[3]; /* pointers to ports */ * ^ *In file included from include/linux/device.h:16:0, * from include/linux/dma-mapping.h:5, * from drivers/net/fddi/defxx.c:206: *include/linux/ioport.h:198:49: warning: ‘*((void *)&bar_len+16)’ may be used uninitialized in this function [-Wmaybe-uninitialized] *-- * resource_size_t bar_len[3]; /* resource lengths */ * ^ *In file included from include/linux/device.h:16:0, * from include/linux/dma-mapping.h:5, * from drivers/net/fddi/defxx.c:206: *include/linux/ioport.h:200:53: warning: ‘bar_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] *-- * resource_size_t bar_start[3]; /* pointers to ports */ * ^ *In file included from include/linux/device.h:16:0, * from include/linux/dma-mapping.h:5, * from drivers/net/fddi/defxx.c:206: *include/linux/ioport.h:200:53: warning: ‘bar_len’ may be used uninitialized in this function [-Wmaybe-uninitialized] *-- * from include/net/net_namespace.h:22, * from include/linux/netdevice.h:44, * from drivers/net/fddi/skfp/h/targetos.h:47, * from drivers/net/fddi/skfp/h/smc.h:50, * from drivers/net/fddi/skfp/srf.c:24: *include/linux/netfilter.h:88:1: internal compiler error: Segmentation fault * }; * ^ *Please submit a full bug report, *with preprocessed source if appropriate. *See <https://bugs.gentoo.org/> for instructions. *scripts/Makefile.build:258: recipe for target 'drivers/net/fddi/skfp/srf.o' failed *make[4]: *** [drivers/net/fddi/skfp/srf.o] Error 1 *make[4]: *** Waiting for unfinished jobs.... * CC [M] drivers/net/ethernet/intel/e1000/e1000_main.o * CC [M] net/ipv6/xfrm6_policy.o * CC [M] drivers/net/ethernet/intel/e1000e/82571.o *scripts/Makefile.build:403: recipe for target 'drivers/net/fddi/skfp' failed *make[3]: *** [drivers/net/fddi/skfp] Error 2 *scripts/Makefile.build:403: recipe for target 'drivers/net/fddi' failed *make[2]: *** [drivers/net/fddi] Error 2 *-- * CC [M] net/sctp/outqueue.o * CC [M] net/sched/sch_prio.o * CC [M] net/sunrpc/addr.o * CC [M] drivers/scsi/scsi_transport_spi.o * CC [M] net/sched/sch_atm.o *scripts/Makefile.build:403: recipe for target 'drivers/net' failed *make[1]: *** [drivers/net] Error 2 *-- * CC [M] drivers/scsi/iscsi_boot_sysfs.o * CC [M] net/sched/em_text.o * CC [M] net/sctp/auth.o * CC [M] net/sunrpc/xprtrdma/transport.o * CC [M] drivers/scsi/advansys.o *drivers/scsi/advansys.c:71:2: warning: #warning this driver is still not properly converted to the DMA API [-Wcpp] * #warning this driver is still not properly converted to the DMA API *-- * CC [M] drivers/scsi/aic7xxx/aic7xxx_core.o * CC [M] drivers/scsi/aic94xx/aic94xx_sds.o * CC [M] drivers/scsi/aacraid/sa.o * CC [M] drivers/scsi/libsas/sas_phy.o *drivers/scsi/aic94xx/aic94xx_sds.c: In function ‘asd_process_ctrl_a_user’: *drivers/scsi/aic94xx/aic94xx_sds.c:597:21: warning: ‘offs’ may be used uninitialized in this function [-Wmaybe-uninitialized] *-- * CC [M] drivers/scsi/qla2xxx/qla_mr.o * CC [M] drivers/scsi/qla2xxx/qla_nx2.o * CC [M] drivers/scsi/qla2xxx/qla_target.o * CC [M] drivers/scsi/qla2xxx/qla_tmpl.o * LD [M] drivers/scsi/qla2xxx/qla2xxx.o *Makefile:947: recipe for target 'drivers' failed *make: *** [drivers] Error 2 *-- * Running with options: all * Using genkernel.conf from /etc/genkernel.conf * Sourcing arch-specific config.sh from /usr/share/genkernel/arch/x86_64/config.sh .. * Sourcing arch-specific modules_load from /usr/share/genkernel/arch/x86_64/modules_load .. * * ERROR: Failed to compile the "modules" target... * * -- End log... -- This doesn't appear anywhere in the log.

Note that the compiler crash happens every time, so this isn't some kind of intermittent hardware problem.
Please attach the output of emerge --info
