I'm building a powerpc cross of gcc-4.2.2 on RH 7.2 host and ran into this:

RHL 7.2 is very old. It is unlikely that we can help you here.

The bug is very hardly reproducable; on FC6 I was unable to reproduce after
running test loop overnight.

If the bug isn't reproducible, then it usually isn't a gcc problem.

There are some rare cases where a bug is only reproducible with the right environment. Different sized environments can cause changes in how stack frames get allocated, which can result in different behavior in the presence of stray pointer reads/writes. If it fails inside make, but not from the command line, it could be such a case.
