Somewhere in the configure of sandbox-1.3 versions (maybe older ones, too), I get this segfault message in my syslog reproducibly: ld[15231]: segfault at 0 ip 0000003335c7e175 sp 00007fffe932d478 error 4 in libc-2.9.so[3335c00000+14b000] In build-x86/config.log, I get: configure:6666: x86_64-pc-linux-gnu-gcc -o conftest -march=native -O2 -pipe -Wl,-O1 conftest.c conftstm.o >&5 collect2: ld terminated with signal 11 [Segmentation fault] /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/../../../../x86_64-pc-linux-gnu/bin/ld: i386:x86-64 architecture of input file `conftstm.o' is incompatible with i386 output Should this really fail this way?

build sandbox with ccache disabled: FEATURES=-ccache emerge sandbox
configure does not segfault with ccache disabled. What is happening when ccache is enabled? Please explain!
I found the discussion and solution myself, thanks. *** This bug has been marked as a duplicate of bug 196243 ***
