gdb is breaking at wrong locations


Hi,

We've got an m68k-coff tool chain to develop for and debug a 68332 board via BDM. I'm using gdb 4.17 and an ICD BDM pod. Today, I noticed that it is not stopping at the set break points. It is stopping about 6 lines after it should, thus it is stopping at times when I don't expect it to. All the break points are at lines the are the else of an if condition and all are a return error; statement. Also, gdb is crashing frequently, or at least it's telling me there's a SIGBUS fault and it cannot proceed.

1) Are there somethings I should look out for when setting break points? Any no-nos?

2) Can I/ should I upgrade to a later version of GDB? Will a newer version work with the older gcc/as/ld/ar tools I'm using now?

As a side note, I've noticed that if I remove the parallel port extension cable between the laptop and BDM pod, the number of crashes decreases. The problem with not breaking at the right location does not go away, however.
