While turning off optimizations to try and track down a compiler bug I noticed that if I used -fno-tree-salias with -O1 the compiler would ICE:
x.c: In function 'main': x.c:1: internal compiler error: in verify_curr_properties, at passes.c:1035 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. This can be reproduced by compiling any program with "-O1 -fno-tree-salias". -- Summary: Using -O1 -fno-tree-salias results in ICE Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: sje at cup dot hp dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33092
