I just tried to compile Suse Linux package MozillaThunderbird-1.5.0.8-7
with the GNU C++ compiler version 4.3 snapshot 20070209.
The compiler said
blocksort.c: In function 'mainSort':
blocksort.c:805: internal compiler error: in vect_get_vec_def_for_stmt_copy, at
tree-vect-transform.c:901
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flags -ftree-vectorize -O2 required.
