Sure, feel free.

Well, sorry, I forgot to mention that I did (reverse gud-debug-log) from
a *ielm* buffer in order to get the value.

AFAIK, it's the `gdb' executable that's distributed by Apple.
I think `Darwin' means many things, but it surely doesn't imply open source.

Indeed, it seems to fix this problem.  Now I'll have to see what's up with
the spurious frames-invalid thing.

IIUC, the thing doesn't do anything useful in GDB < 6 anyway, right?
On the macosx version it leads to bad behavior, but on other systems it's
just caught as an error and ignored, right?
Then how abour "parsing" the "welcome message" to see if we're dealing with
GDB >= 6 ?  Or otherwise how about moving this to the gdbmi insterface?
