Re: exception handling and conservative GC

Benjamin,

I looked at that bug report.  I don't see what it has to do with  
ours.  (Your bug deals with unregistering pthread specifics.  I'm  
talking about which malloc function is used to allocate in-flight  
exceptions.  These are orthogonal concerns.)

I just looked at the latest from SVN.  The code that I'm interested  
in hasn't changed, so my patch still applies.  I can't get the  
compiler to compile on my AMD64 machine, so I haven't had a chance to  
verify that the problem still exists, but from looking at the code,  
I'm sure it still does.
