Definitely, I will look into the details of build configuration.

I complied boost myself and the runtime settings are all same: /MD
I have a main application (exe)
a pyd
and boost_python-vc80-mt-1_36.dll

I tried setting strings to 30 chars in the constructors to force the size
allocation in another way but no change same problem.

name= "1234567890123456789012345678901234567890";



I do not know if it fails while deleting but it booms just during
assignment.  I dont think it reaches delete time.

Do different configured PCs have different memory allocation routines?
Because a friend of mine tested the application on a different computer
running same os (vista) without anyproblems.
