#3113 z80 (and related) assembler segfault

[Philipp Klaus Krause]

Trying to compile the following code

typedef struct {int x;} s;

s   _s;

void f(void)
{
__asm
    ld  b, #_s+6-_s
__endasm;
}

for a z80-related port, such as z80 or r2k, results in a segfault in the assembler.

[Sergey Belyashov]

Fault is caused by line asxxsrc/asout.c:525 because esp->e_base.e_sp == NULL. Function is called from asz80/z80mch.c:1126.
