Huh, we can't even print out the error message correctly, apparently.
Does this look familiar to anyone?

Yes, but I will not be of any help 8-(
The bug happens a lot when using the CDT IDE,
We make use a lot of the MI commands -data-xxx-register
to give feedback to the user.
On certain platform & OS, probing the registers
can have disastrous effects on GDB, usually internal-errors.
It happens on Solaris, ARM and to a lesser extent GNU/Linux on x86
The one below was seen on Solaris 8.
Our usual response, in the Eclipse/CDT mailinglist/newsgroup,
was to turn off registers automatic refreshing and fire a PR
to GDB GNATS 8-).

Got a PR number? I only found things like this:
http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gdb&pr=1223
which I think are fixed.

Anyway, a quick glance at the code reveals:
if (! frame_register_read (DEPRECATED_selected_frame, regnum,
raw_buffer))

By the way, the garbled error message was present on the 6.0 branch on
6/29, but is gone as of 8/1. Don't know what caused that.

This?
2003-06-30 Andreas Schwab <schwab@suse.de>
* utils.c (internal_vproblem): Use xvasprintf, not xasprintf, to
format error message.
2003-06-26 Andrew Cagney <cagney@redhat.com>
* utils.c (internal_vproblem): Print the problem to a reason
buffer and then pass to query. Make the msg variable more local.
Turned out my compiler didn't detect the typo, but Andreas's compiler did.

Aha! Thanks very much, that explains it. Just my bad timing for a
snapshot...
