Alex,
It looks like there definitely is some sort of memory corruption going
on with your system. It's strange that this isn't more widely
reported if it is a problem with the code. globals->get_props()
can't be non-zero at this point in the code. Are you running out of
RAM or something?
main.cxx line # 1431 is where globals is created. Could you print out
the value right after that to see if the 'new' was successful? If
it's breaking down there, you aren't going to get much further before
the code crashes.
Curt.
