Thanks for the response. The 'analyzer' program is statically linked; 
it involves no DLLs. Rebaseall did nothing. And increasing the size 
of the heaps did nothing (I tried 2x, 4x, 8x and 16x). My machine is 
totally wedged now...even safe mode doesn't work.


I can only say that this fork problem happens on several other 
Windows machines at our university, but it does not seem to happen to 
machines not at the university. Furthermore this fork problem now 
affects previous versions of my 'analyzer' software...last week's 
version worked then, but does not now. It's as if  Satan put a curse 
on all the PCs only at this university.


Any other suggestions?




Trying a snapshot it a good subsequent step.  If you're going to be 
building
things against Cygwin, you'll want to pull the cygwin-inst.  
Otherwise, cygwin1-*.dll is enough and is probably plenty for starters.



http://cygwin.com/snapshots/



Well, the latest snapshot available is 2005-Nov-17. Planting its
cygwin1.dll into cygwin/bin generates the following result:

   analyzer --KANTOO_LANGUAGE=halo --ANALYZER_PORT=4052 
-server-multiple -fork

   Analyzer 2.0; DMK 0.2 (HALO); DOMO 0.2 (KCE)
 6 [main] analyzer 2164 
fhandler_disk_file::fixup_mmap_after_fork: requested 0x1873 != 0x0 
mem alloc base 0x1873, state 0x1000, size 4096, Win32 error 487
   d:\svoboda\kantoo\bin\analyzer (2164): *** 
recreate_mmaps_after_fork_failed

   ]0;~
   [EMAIL PROTECTED] ~
   $

which is a slight improvement over the previous result:

   [EMAIL PROTECTED] ~
   $ analyzer --KANTOO_LANGUAGE=halo --ANALYZER_PORT=4052 
-server-multiple -fork

   Analyzer 2.0; DMK 0.2 (HALO); DOMO 0.2 (KCE)
 6 [main] analyzer 224 
fhandler_disk_file::fixup_mmap_after_fork: requested 0x1873 != 0x0

11 [main] analyzer 1136 fork_parent: child 224 died waiting for 
dll loading

   Failed to fork properly!
   ]0;~
   [EMAIL PROTECTED] ~
   $

but still crashes my analyzer.

My best guess is that this bug was introduced by a new version of
cygwin, as it did not occur until I did a cygwin-update.

It seems that the oldest cygwin I can get is 1.5.17.1, (1.5.18.1 being 
the current version) Is there any way to get older c ygwins?

But didn't you claim that switching back to an older version of Cygwin
didn't help?

There's the Cygwin Time Machine.  Look it up in the email archives if you're
interested.  And note that use of the Cygwin Time Machine isn't supported by
this list.
