Very strange. For two reasons. First of all, why is the mismatch
message printed at all? The code in question is basically:
if (res->cygheap != (void *) &_cygheap_start)
multiple_cygwin_problem (...);
But res->cygheap and &_cygheap_start are apparently identical, so why
is multiple_cygwin_problem called?
And then multiple_cygwin_problem calls api_fatal to print the message
which means that ultimately TerminateProcess() is called.
I tried that on my XP64 test machine and cygcheck worked fine.
Could you do a parallel installation on the same machine and see how it
behaves there?
