I'm trying to run my 32-bit app through Valgrind (It's still required to be 32-bit by some dependencies unfortunately), and it's tripping over an instruction.

10.7.4 if it matters.

Comment 2 seth 2012-09-06 17:33:10 UTC

Duplicate. I really thought I looked throughly at every result, but further searching eventually lead me to bug 295974 which appears to cover my case.
