Description Jonathan Briggs 2005-02-15 23:20:00 UTC

Segfault inside the compiler.

The command to reproduce is:
i686-pc-linux-gnu-g++ -O3 -march=athlon-mp -ftree-vectorize /tmp/j1.cpp

It does not happen if either -ftree-vectorize or -march=athlon-mp is left out.
I will attach the preprocessed source file causing the problem.

Please report upstream (http://gcc.gnu.org/bugzilla/) and add here a link to the bug.

Comment 3 Jonathan Briggs 2005-02-16 06:30:32 UTC

Ah, okay.  The gcc error message said to report the bug here.  I thought maybe the GCC team didn't want to hear from Gentooers.

If is a supported gcc we take the bug and report upstream if necessary, if is a yet to be supported snapshot from an alpha branch we prefer to have the issue reported directly to upstream.
