The following code causes a segfault:

typedef int32_t (*ProcPtr)();
void Dispatcher(int32_t startCode)
{
  if (rcvArgs.bytesReceived <


This doesn't look to me like either bug 22604 or 23118.  It's a Delta-reduction from a file for a 
different bug (internal compiler error: tree check: expected class ‘type’, have ‘exceptional’ (error_mark) 
in build_pointer_type_for_mode, at tree.c:4246) which I'm still working on.

Here's the session:
