I have built a C++ server program called 'analyzer'. But when I try to

If running 'rebaseall' doesn't help (see the README) and 'analyzer'
doesn't
use any DLLs that were built as part of that package (in which case you
need to tell 'rebaseall' about them), then try:

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

which is a slight improvement over the previous result:

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?
