[hrompato]

same thing in my instalation, any idea?

[hrompato]

I've downgrade to version 7.11-1 and gdb returned to work. Obviously the problem is the version 7.12

[mwhessel]

I have the same issue, downgrade to version 7.11-1 and gdb returned to work ...

[mwhessel]

Still the same issue with gdb 7.12.2 :(

[orgads]

Easily reproducible by typing an invalid command.

Looks like a C++ exception is thrown by error(), but it is not catched in catch_errors().

[genusistimelord]

thank you for this fix as well this also was another fix that helped prevent crashing of GDB with IDE's.
