This is the most common failure on both ppc32-aix and ppc64-aix. It seems to impact about 1 test every other run (ie, about 0.5 tests on average).

One instance is: http://jikesrvm.anu.edu.au/cattrack/results/piccolo.watson.ibm.com/core-ppc32/4370/prototype/default/dacapo/xalan

I suspect a problem is that if a GC happens at this program point we're making a mistake when interpreting the stackframes, but it's possible that there is some other problem (or that this is an indirect crash caused by the current known problems of Identity HashMaps in the bootimage).
