I am still seeing this in the 20020120 source. I am trying to debug
Mozilla with gdb, but if the code is like this:
1 int i, j;
2 i=1;
3 j=0/i;
4 i=1; // the code beyond line 3 does not really matter
when I do "nexti" commands starting at line 2, I get:
> 2 i=1;
> (gdb) nexti
> 0x200040adc18 2 i=1;
> (gdb) nexti
> 3 j=0/i;
> (gdb) nexti
> 0x200040adc20 3 j=0/i;

I tried a simpler program with just the lines of code that seemed to
matter, but that worked ok (possible a pthread issue)
The system I am running on is an Alpha, RedHat Linux 7.1,
kernel-2.4.9-12, gcc-2.96-87 (and gcc-c++), glibc-2.2.4-19.3 (and
glibc-devel)
I see this with gdb-5.0rh-9, gdb-5.1-3(rawhide) and today's source.
