[MLton-devel] testMatrix regression segfault

[Stephen Weeks]

The changes over the last 24 hours have introduced a bug that causes a
segfault in testMatrix.  The bug only happens when compiling -native
true, so it may be native codegen bug.  In investigating a little, I
see that the problem is that a limit check is failing and GC_gc is
being called, even though the frontier should be well below the limit.
You can verify this by running @MLton fixed-heap 100m --.  With a
print statement, I can see that the limit is zero.  This makes no
sense, since this program doesn't use signals or the like.  Any ideas?
