Attached is a sample from OpenSSL. When compiled with -O3 the error comes up.
I tried to remove as much code as I could, but it looks like every line I remove also avoid the error. I use rev141361 -- Summary: internal compiler error: in vectorizable_store, at tree- vect-transform.c:5447 Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: alon dot barlev at gmail dot com GCC host triplet: i686-pc-linux-gnu GCC target triplet: x86_64-pc-mingw32 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37955
