Re^3: [Win32] pthreads and memory allocation

Another thought. If you add #undef malloc just prior to your use of malloc, you may find that the code will run without immediately crashing. But I make no claim that you won't run into similar problems later on.

add #undef malloc just prior to your use of malloc Ooow .... I like that idea :-) I've actually placed the '#undef malloc' at the very start of the C code in that script, and the script now runs fine. Beyond that, nothing has yet been established. Now it's just a matter of seeing whether the same approach can help with PDL (which is where the actual problem that prompted this thread lies.) Cheers, Rob	[reply]

But be careful. You can find yourself in the 'multiple C runtimes' trap passing pointers allocated by one to another to be freed with various possibilities of outcome. BTW. You should also be very wary of passing pointers to memory allocated on the stack of one thread as the thread argument to another. I realise it was only demo code, but it's worth a heads up.
