Crash while running uTorrent 1.8.2

[anonymous]

The VM crashes running uTorrent.

It looks like 2 threads are in free() at the same time... maybe a threading bug?

I'm running Windows 2003.

just tested 3.0 and i get the same crash.

[vasily Levchenko]

Thanks for report. Could you please attach the log?

[anonymous]

sorry, i've added it.

[vasily Levchenko]

Have you been able get crash dump? if yes please let me [vasily _dot_ levchenko _at_ Sun _dot_ COM] know, I'll provide instruction how to deliver it to us.

How do I generate a crash dump?

I can replicate the problem.

[vasily Levchenko]

please check C:\Windows\Minidump or %SystemRoot%\Minidump.

[anonymous]

nope, no dumps. i have confirmed that my o/s options are set to create dumps, but there are none.

i guess this is to be expected because it is VirtualBox that is faulting, not the O/S.

when the crash happens i get a "VirtualBox.exe - Application Error" OK/Cancel dialog box in the host o/s that allows me to attach a debugger to the process. that is how i got the stack trace for the faulting thread.

Does it repeat in 3.0.2?

[anonymous]

Seems to be fixed in 3.0.2. Thanks.
