Trouble with pgrep - *** fatal error - called with threadlist_ix -1

[Sean McNamara]

Hi all, 

I'm having some trouble with some scripts that we are trying to run in cygwin.  These scripts work fine on both Unix and Linux boxen, but when trying to do a "pgrep" in the script, get a fatal error.  I've tried to find an answer in the archives and via google but either it's not a commonly encountered issue, or my keywords are poor....

I can re-create the error from a command line.  Below is an example:

-------------------------------------SNIP-------------------------------------------------

[557] /c/dev/apps/bin
$ ps ax
      PID    PPID    PGID     WINPID  TTY  UID    STIME COMMAND
     2160       1    2160       2160  con 25282 10:33:03 /usr/bin/bash
     5272       1    2496       3236  con 25282 10:33:23 /usr/bin/sh
     2316    5272    2496       5820  con 25282 10:33:24 /usr/bin/sh

[558] /c/dev/apps/bin
$ pgrep -P 2160
     28 [sig] pgrep 3292 C:\cygwin\bin\pgrep.exe: *** fatal error - called with threadlist_ix -1
Hangup

Can anyone give me some pointers on what might be going wrong here?

Thanks!
