I don't think the fix is completly correct... in all cases, we need to
keep the current heap... if the debugger continues the execution, then
the old heap is needed (for example, HeapFree/HeapValidate will no
longer work...)
so, a proper fix (to deal with this situation) would be to:
- set a new heap (as you did)
- create the process for the debugger, but suspended
- put back the old heap in the pdb
- fire the debugger (ResumeThread)
note anyway that the fix isn't perfect. for example, if an execption
results from a corrupted heap, we may still use heap related functions
in the exception handling code (the debugger startup is one of example,
but is far from being the only one). For example, running with
-debugmsg +seh is another one :-/
