Comment:
OK, the good news is that it looks like the program is now segfault-free
on Linux and Windows, with this additional patch:
{{{
Fri May 23 04:25:08 BST 2008 Ian Lynagh <[EMAIL PROTECTED]>
* Do some stack fiddling in stg_unblockAsyncExceptionszh_ret
This fixes a segfault in #1657
}}}
The bad news is that Simon Marlow says that the behaviour (that a single
throwTo causes the computation not to be resumable) is expected given the
way exceptions are currently implemented.
