random binary crashes, generally while compiling or doing other port work

[kallisti5]

I've been seeing random application crashes from things that generally don't crash. (sh, python, etc)

I don't think these are isolated issues as in the case of each crash, if I run the task again it generally works. I've been collecting these debug reports and are attaching them to this case.

All of the crashes seem to be memory related in some way... and i've seen the crashes across multiple installations of Haiku.

System:

x86_gcc2
hrev46452, hrev46472 and earlier revs.
AMD Bulldozer, 8 core, 16GB ram.

This all could be leftover from the PAE mess, not sure though.
