Subject: [ruby-core:30962] [Bug #3501] Segmentation Fault in vm_xmalloc (apparently)

Issue #3501 has been updated by Lukas Oberhuber.


Well, I spoke too soon, as 1.9.2 preview 3 has also segfaulted. Here is the partial stack trace (the process froze and had to be kill -9 ed to shut down). Unfortunately I don't have a reliable test case. Maybe memory is being corrupted.
