Hi,
    I am trying to call an external assembly procedure from within a C
program but I keep getting stack faults and GPFs. The assembler used is
NASM, I'm assembling to COFF format and linking correctly. Here is the
code:

main.c:

extern void asm_test(void);

int main()
{
    asm_test();
    return 0;
}

asm.asm:

bits 32
section .text

global _asm_test
_asm_test:
    ret

NASM uses global in place of public and since I declared "bits 32" it
will use the correct form of the ret instruction (retd on most
assemblers).

Thanks,

Bart Trzynadlowski
