Re: Three ICEs in regression tests with gcc-3.4-20030813

First, a problem that shows up on both powerpc variants. The summaries

show:
FAIL: gcc.dg/altivec-5.c (test for excess errors)
The log shows:
gcc-3.4-20030813/gcc/testsuite/gcc.dg/altivec-5.c:12: internal compiler error: in extract_insn, at recog.c:2064

Hmm. That error message looks like the one in http://gcc.gnu.org/PR11699 but the fix for that one was MIPS-specific. Here's a more complete log extract.

Please submit a full bug report,
with preprocessed source if appropriate.

Shall I pull out the preprocessed source, or
is it enough to point people to my build script?
