Bug 277312 – sys-cluster/pvm segfaults after compilation with gcc-4.x

• Status: RESOLVED DUPLICATE of bug 151316
• Product: Gentoo Linux

[Description Alexander Prokofiev 2009-07-10 12:52:50 UTC]

pvm utility segfaults on start when compiled with gcc-4.
This seems to be because of the way newer gcc treats not
correct code.
This happens with pvm-3.4.5. I've not checked newer pvm-3.4.6

This patches helps:
