signal 6 while compiling

[Mark Davies]

While compiling linux 2.1.9[12] with egcs980328 (cvs) I got a signal 6
when compiling
3c503.c. I've stripped the source as much as I can and replicated it
below.

I also get the same problem while compiling regex on glibc2


Mark.





#include <linux/netdevice.h>
#include <linux/etherdevice.h>

// comment this out and it compiles ?
#include <asm/io.h>

#include "8390.h"
#include "3c503.h"


// gives error - function type not a prototype
static void
el2_block_input( );

void dummy();

    int count;
    int ring_offset;

// removing these variables and changing the memcpy below compiles ok.
    int end_of_ring = dev->rmem_end;
    int semi_count = end_of_ring - (dev->mem_start + ring_offset);

// comment this out and it compiles - with or without changing the lines
