The problem appears to be cygwin 1.7-specific. (*)

I get a stackdump as follows. I find that I get a stackdump under a
cygwin shell (DOS terminal) but not under mintty so I'm not 100% sure
the stackdump is for the correct error.

I was able to get a further stack trace from gdb from that. Again, it
would only happen on a cygwin shell and not mintty so I'm not sure I
copied the correct error:

(*) I know that doesn't mean that it's 1.7's fault. Perhaps the
problem was pre-existing and was only revealed in 1.7. But it works in
1.3 and 1.5 on WinXP and fails in 1.7 in WinXP-32, Vista-32, Win7-67.
