This may or may not help:

According to VC++ debugger it always dies with:
Unhandled exception at 0x610d089d in perl.exe: 0xC0000005: Access violation reading location 0x00000004.

According to gdb 0x610d089d = thread.cc:113

So running it through gdb it hits this break point ~ 280 times before it exits:


[gdb]
