Thread: windows builds hanging on regression checks

Something committed in about the last 24 hours or so has caused my 
Windows buildfarm members to hang completely while running the 
regression tests. It's happened for both MinGW and MSVC builds.

To get the buildfarm run to complete in some fashion, I had to kill 2 
psql processes, and then 2 dwwin processes. The result was this: 
http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=dawn_bat&dt=2008-05-17%2012:28:51

The most likely candidate looks to me like this one :"Implement error 
checking for pthreads calls in thread-safe mode." but that's just a guess.

cheers

baiji and dawn_bat are both green now, so apparently Stefan was correct
to guess that the array indexing bug in psql/print.c was the problem.
I don't understand, however, how that manifested as a hang and not
a core dump.  Does Windows not treat bogus pointer dereference the
same as everyone else does?

Yes, it does. What hung apparently was the Dr Watson error reporting 
tool. I think I've disabled it for everything but the OS now.
