Possible bug in gdb 6.7.1

Possible bug in gdb 6.7.1

[Joel Sherrill]

Hi,

I accidentally did something stupid and think I tripped a bug in
gdb.  I was on an i386 target remotely debugging using a
remote target to qemu.  I switch targets a lot and accidentally
looked at $pc instead of $eip.

(gdb) p/x $pc
../../gdb-6.7.1/gdb/regcache.c:164: internal-error: register_type: 
Assertion `regnum >= 0 && regnum < descr->nr_cooked_registers' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) n

Seems a little harsh for a bad register name from the
command line, doesn't it. :D

Try GDB 6.8, which should fix this.

Wow! That was quick.  You fixed it and made a release. :-D

Is the gdb webpage right now? The 6.8 news is there but the
download link above it still says 6.7.1.

Thanks for the quick reply.

Thanks for pointing this out. I missed it when I last updated
the web pages, but it should now be fixed.  Thankfully, the target
links were OK.
