Preremove/postinstall scripts fail with snapshot installed


If I run setup.exe with a cygwin snapshot installed, bash crashes while running all preremove and postinstall scripts. Here's a typical error message in /var/log/setup.log.full:

2011/02/11 15:56:55 running: C:\cygwin\bin\bash.exe --norc --noprofile /etc/preremove/emacs-X11.sh
0 [main] bash 2760 exception::handle: Exception: STATUS_ACCESS_VIOLATION
1739 [main] bash 2760 open_stackdumpfile: Dumping stack trace to bash.exe.stackdump


I can reproduce this on two different Win7 machines, but the problem doesn't occur on a third machine running XP SP3. I'm attaching cygcheck output from one of the Win7 machines, as well as a bash stackdump.

I've tested this on the latest snapshot (2011-02-07) as well as the 2010-12-01 snapshot. I haven't yet had a chance to test earlier snapshots to see where the problem first occurs, but I'll try to do that over the weekend. The problem does not occur under cygwin 1.7.7.
