Dynamic malloc problem

[clifford.smith]

Hello,

I am writing a chess prog and I have the following problem:

sine I allocate memory with malloc for table in the main() it works
perfectcly. As soon as I try to allocate this memory in a function (void
my_funct() ... ) I get a segm. fault.

What can I do. Is there another way to dynamicaly allocate mem ?

Thanks,
serge;
