--- Comment #2 from Scatterlogical <scatterlogical gmail com>  2009-09-29 04:58:46 ---
Crash reproduced with MALLOC_CHECK_=0.
Although this time it manifests itself as a segfault since malloc-check isn't
catching it and aborting, but the trace is essentially the same. I would be
inclined to think that anything that gets dug up by the check is a bug anyway,
the check just catches invalid memory operations before they escalate into
something worse, does it not? I don't think the solution is to disable
something that is being strict about correct program operation in an attempt to
sweep a bug under the rug (scuse the expression).
