Os: MacOS X | Architecture: x86
---------------------+------------------------------------------------------
Searching trac for "ASSERTION FAILED" or Evac.c didn't turn this up, so
here goes.
I've been infrequently getting this on startup:
{{{
seq: internal error: ASSERTION FAILED: file sm/Evac.c, line 368
(GHC version 6.10.4 for i386_apple_darwin)
Please report this as a GHC bug:

}}}
This is OS X 10.5.8. Starting the same program again with no changes
works, so I can't trigger it consistently. Here's the traceback from the
crashing thread:
