Cog-r2491 crashes

Andrew Gaylard
 
Hi VM developers,

I'm finding the Cog VM, r2491, built from SVN source on Ubuntu-10.04,
crashes from time to time, apparently under load.

I've included the top 40 lines of the debug traces for four of these crashes.

Anyone have any ideas?

Re: Cog-r2491 crashes

Eliot Miranda-2

:(.  I made significant changes recently to gc in machine code and to MNU handling. But this could also be Linux.  Try compiling with -O1 and see if any different.  Also, what's the last stable version for you?  

Of course, gold is a reproducible case...
 Is this easy to configure?  If so, I could run a replica under the debugger and take a look when it crashes.
