Question on setting stack size KMP_SET_STACKSIZE_S

Hi All,

I would like to set the stack size at runtime for my parallel project. The stack size (e.g., 100000000) was previously set through property/linker/system/stack reserve size and stack commit size, and it works fine.

But when I set the stack size at runtime, it can not work and throw out "stack overflow". The codes are as follows:

stack_size = "estimate stack size" (e.g., 100000000)

call KMP_SET_STACKSIZE_S(stack_size)

write(idbg, *) "set stack size to: ", stack_size

stack_size_check = KMP_GET_STACKSIZE_S()

write(idbg, *) "check stack size:", stack_size_check

The result shows that  the stack size has been set to 100000000, but still cause stack overflow problem.

What's wrong with the above codes?

Thanks and regards,

Daniel
