I think this problem needs a Solaris wizard.  But I suspect the
problem is related to unexec or to use of malloc.

If you see that some Emacs versions work and some fail,
you could try looking for differences between them
that are in unexec or the code that uses malloc, or in the
flags that control these things.  By installing some subsets
of those differences, you might be able to see which ones
trigger the problem.  That would be a good step towards
solving it.
