Since 4.4 i'm unable to rebuild gcc, check downstream bug: http://bugs.gentoo.org/286251
Steps to reproduce: - extract gcc-4.4.1 tarball -./configure -make LDFLAGS=-Wl,-O1 STAGE1_CFLAGS=-O LIBPATH=/usr/lib/gcc/armv5tel-softfloat-linux-gnueabi/4.4.1 'BOOT_CFLAGS= -march=armv5te -pipe -O2' bootstrap-lean -segfaults The failing part is as follows: hecking for armv5tel-softfloat-linux-gnueabi-ar... /usr/armv5tel-softfloat-linux-gnueabi/bin/ar checking for armv5tel-softfloat-linux-gnueabi-lipo... lipo checking for armv5tel-softfloat-linux-gnueabi-nm... /var/tmp/portage/sys-devel/gcc-4.4.1/work/build/./gcc/nm checking for armv5tel-softfloat-linux-gnueabi-ranlib... /usr/armv5tel-softfloat-linux-gnueabi/bin/ranlib checking for armv5tel-softfloat-linux-gnueabi-strip... /usr/armv5tel-softfloat-linux-gnueabi/bin/strip checking whether ln -s works... yes checking for armv5tel-softfloat-linux-gnueabi-gcc... /var/tmp/portage/sys-devel/gcc-4.4.1/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.4.1/work/build/./gcc/ -B/usr/armv5tel-softfloat-linux-gnueabi/bin/ -B/usr/armv5tel-softfloat-linux-gnueabi/lib/ -isystem /usr/armv5tel-softfloat-linux-gnueabi/include -isystem /usr/armv5tel-softfloat-linux-gnueabi/sys-include checking for suffix of object files... configure: error: in `/var/tmp/portage/sys-devel/gcc-4.4.1/work/build/armv5tel-softfloat-linux-gnueabi/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[2]: *** [configure-stage1-target-libgcc] Error 1 make[2]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.4.1/work/build' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.4.1/work/build' config.log contains: configure:2415: /var/tmp/portage/sys-devel/gcc-4.4.1/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.4.1/work/build/./gcc/ -B/usr/armv5tel-softfloat-linux-gnueabi/bin/ -B/usr/armv5tel-softfloat-linux-gnueabi/lib/ -isystem /usr/armv5tel-softfloat-linux-gnueabi/include -isystem /usr/armv5tel-softfloat-linux-gnueabi/sys-include -o conftest -g -march=armv5te -pipe -O2 conftest.c >&5 conftest.c: In function 'main': conftest.c:15: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

This doesn't occur on 4.3, 4.3 is able to compile 4.4, but 4.4 is unable to compile itself or gcc-4.3. Not sure if its related, but i filed bug 40105 for SH some time ago, and using -O2 in STAGE1_CFLAGS made it work. Thanks, let me know if you need more info. -- Summary: [4.4 Regression] ARM: 4.4 compiler segfault when compiling gcc Product: gcc Version: 4.4.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: armin76 at gentoo dot org GCC host triplet: armv5tel-softfloat-linux-gnueabi http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41500
