Subject:	BASH crashes upon exiting function?

I'm attempting to build a project (CMake, specifically, to get it ported
for DJGPP!) and BASH is blowing up on its "bootstrap" script.  I've gone
over the mailing list already, and I've tried running it on both a Win2K
and a Win98 system.  On my Windows 2000 system I've tried both djdev203
with BASH 2.04, the djdev204 in the v2/beta directory with BASH 2.04, and
that djdev204 with the BASH 2.05b from clio.rice.edu.

All of those configurations failed in exactly the same way, even if I
modified the bootstrap script to skip steps - the first time it hits a
return (i.e., from a shell function) BASH crashes, according to what I
see from set -x.

The crashdump looks like the following, for BASH 2.05b:

I have nothing in my PATH but C:\DJGPP\BIN; I've set the first line of
the bootstrap script to #!/bin/bash, just to make sure that there was
nothing wrong with /bin/sh.

Is this a problem that anybody's ever heard of?

Thanks for your help... if I can get this working, I'll be able to add a
good cross-platform tool to the DJGPP arsenal!
