I just tried to compile the Suse Linux package zvbi-0.2.33 with the gcc 4.5 mainline snapshot 20090903 and the compiler said
exp-txt.c: In function 'print_char': exp-txt.c:684:1: internal compiler error: in propagate_subacesses_accross_link, at tree-sra.c:1563 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Preprocessed source attached. Flag -O2 required. Minor cosmetic problem: It will be better English to rename propagate_subacesses_accross_link to be propagate_subaccesses_across_link -- Summary: ice in propagate_subacesses_accross_link 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 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41301
