I just tried to compile the Suse Linux package qemacs-0.3.1-380.42 with the GNU gcc version 4.5 snapshot 20090528.
The compiler said gcc: Internal error: Segmentation fault (program cc1) Please submit a full bug report. See <http://gcc.gnu.org/bugs.html> for instructions. Preprocessed source code attached. Flag -O3 required. Here is some valgrind output which might help ==8522== Stack overflow in thread 1: can't grow stack to 0x7FE801FF8 ==8522== Can't extend stack to 0x7FE801700 during signal delivery for thread 1: ==8522== no stack segment ==8522== ==8522== Process terminating with default action of signal 11 (SIGSEGV) ==8522== Access not within mapped region at address 0x7FE801700 ==8522== at 0x96B07A: cgraph_clone_inlined_nodes (ipa-inline.c:261) ==8522== Invalid write of size 8 ==8522== at 0x4A1F3A8: _vgnU_freeres (in /usr/lib64/valgrind/amd64-linux/vgpreload_core.so) ==8522== Address 0x7fe801f70 is on thread 1's stack ==8522== Stack overflow in thread 1: can't grow stack to 0x7FE801F70 ==8522== ==8522== Process terminating with default action of signal 11 (SIGSEGV) ==8522== Access not within mapped region at address 0x7FE801F70 ==8522== at 0x4A1F3A8: _vgnU_freeres (in /usr/lib64/valgrind/amd64-linux/vgpreload_core.so) -- Summary: possible failure in cgraph_clone_inlined_nodes with -O3 Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: dcb314 at hotmail dot com GCC host triplet: x86_64-suse-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40298
