David Chisnall <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|FIXED | --- Comment #9 from David Chisnall <[email protected]> 2009-11-14 12:30:51 --- This bug went away for a bit, but it seems to have reappeared with recent versions. There seem to be a couple of problems. The original test case that I uploaded now crashes with a failure in new, and this trace: #0 0x2974ede7 in kill () from /lib/libc.so.7 #1 0x29540347 in raise () from /lib/libthr.so.3 #2 0x2974d91a in
