Issue 1169108: PySys_WriteStderr() -> WaitForSingleObject() hangs system (original) (raw)

hello,

I am running Simpy (python simulation framework) within pythondotnet (a slightly modified python version, based on python2.4), and, even though this process is single-thread, it hangs misteriously, in an unpredictable way...

Python console cease to respond to Ctrl-C events...

Here is the current Thread status:

Thread Start Address: Symbol Name: Line Number: PC: mscoree!_CorExeMain() + 0x0 --- 7917D08C

Thread Stack:

ntdll ! KiFastSystemCallRet() + 0x KERNEL32 ! WaitForSingleObject() + 0x12 python24 ! PySys_WriteStderr() + 0x14d python24 ! PyTuple_Type() + 0x0

However, I would like to be able to go higher in the stack, to see what caused this deadlock.

Any proposed strategy to guess what happened, or to track down the problem?

thanks a lot,

Stan.
