When trying to install the newest GCC (gcc-4.3.0_alpha20070126) the build process dies during configuration. This is due to a test that makes the compiler do an internal error (segfault). Reproducible: Always Steps to Reproduce: 1. Create an ebuild that uses gcc-4.3.0_alpha20070126 2. Try to ebuild it with the use flags: "fortran gcj gtk nls (-altivec) -bootstrap -build -doc (-hardened) -ip28 -ip32r10k -mudflap (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla" 3. Watch and wait, the error takes place when we are to build libgcc.

Expected Results: Successfull compilation and installation of GCC. I tried to run the test program that result in the segfault with the xgcc binary: ------------------------ conftest.c ------------------------ /* confdefs.h. */ #define PACKAGE_NAME "GNU C Runtime Library" #define PACKAGE_TARNAME "libgcc" #define PACKAGE_VERSION "1.0" #define PACKAGE_STRING "GNU C Runtime Library 1.0" #define PACKAGE_BUGREPORT "" /* end confdefs.h. */ int main () { ; return 0; } ------------------------ conftest.c ------------------------ with this command: /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070126/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070126/work/build/./gcc/ -B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ -isystem /usr/i686-pc-linux-gnu/include -isystem /usr/i686-pc-linux-gnu/sys-include -c -O2 -march=pentium3 -pipe -O2 /tmp/conftest.c This did result in segfault, so I guess the xgcc that is build during compilation of GCC has errors.
Created attachment 108851 [details] gcc-4.3.0_alpha20070126.ebuild This is the ebuild I used.
Created attachment 108853 [details] xgcc (executable) This is the executable that configure tries to use, it came from: /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070126/work/build/./gcc/xgcc
Created attachment 108854 [details] config.log (libgcc) This is the log file from configure. It came from: /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070126/work/build/i686-pc -linux-gnu/libgcc/config.log
Not a bug in anything provided by Gentoo, so closing INVALID.
