swapstack crash at exit

[BSzili]

I have an issue with swapstack.o as it causes a crash when the program exits, but only when the stack was replaced. I crated a minimal example program:

extern void __stkinit(void);
void * __x = __stkinit;
unsigned long __stack = (32*1024);
int main(void)
{
    return 0;
}

compile with: m68k-amigaos-gcc -noixemul -m68060 -m68881 -ffast-math -O2 -fomit-frame-pointer -o stkswap stkswaptest.c /opt/amiga/m68k-amigaos/libnix/lib/libm020/libm881/swapstack.o

It would also be convenient if swapstack.o was included in libnix20.a too and not just libnix13.a. That way there would be no need to specify the absolute path to have the correct version of swapstack. It shouldn't cause any issues for existing programs, as it wouldn't get linked unless __stkinit is referenced.

the idea of including the file allows you to omit

extern void __stkinit(void);
void * __x = __stkinit;

That would be even better, like it is in MorphOS, where you only need the unsigned long __stack global variable.
