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-).
