<div>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-family:"Calibri","sans-serif"">  I was trying to get a handle on that problem last year. The threadtest program is really a stress tester of the collector/allocator with pthreads. If you run it

 with just the tests read and alloc you pretty much always get a crash. If you run them with paranoidgc it will crash in the heap checker. Tony thought it was a clear cut  problem of the roots of some ref not being found on a thread stack. I mucked around with

 code to get some output and the stacks looked ok to me but I could be wrong. All stacks are checked whilst the threads are blocked in a signal handler, the design of which looks fine as far as I can tell. This test is characterised by some slow threads (the

 read threads) and a bunch of fast threads (the alloc threads). Even if you modify the test to have only one read thread the problem occurs. I have had misgivings about mixing signals and threads having been bitten many years ago, but really this is the only

 way the collector can get its raw refs to check.<span class="ecxapple-converted-space"> </span><br>

My guess is its a subtle timing or lock problem maybe a lurking bug in the collector itself. One thing I noticed is that in ThreadPThread__ProcessStopped  the second call to   p(context, ((char *)context) + sizeof(ucontext_t)); according to the comment is to

 process the registers. But the registers should already be on the stack and anyway this call is a partial duplicate of the previous one.<o:p></o:p></span></p>

I figured there aren't actually implementations of Word.Xor, Word.Or,<br>

BTW, any idea about what's wrong with pthreads?  Do you think the issue<br>
