RE: bash hangs on WinNT Service Pack 5

[Lance Zaklan <lance at intertrust dot com>]

I'm seeing the same problem on Windows NT service pack 4 same versions
of cygwin and bash.  The build system is a modified gmake which 
uses a translater to convert .dsp and .dsw to gnu make files.  The
build is control by a perl script.  The behavior I observe is a sub-task
of the make process (often echo) goes into a loop burning cpu.  Killing
the looping echo program, results in all other bash shells getting
the no more processes error.  Interestingly, simple commands running
in a bash shell will hang.  When I attempted to ^C a stuck ls command
i got:
[main] c:\cygnus\CYGWIN~1\H-I586~1\bin\bash.exe 1000 (0)
lock_pinfo_for_update: rc 258, error 6


thanks
