Description Christophe Fergeau 2014-10-12 12:29:07 UTC

Getting this error fairly reliably when trying to step through a program (test-unlock-keyring from gnome-keyring source) with gdb on f21 (gdb-7.8-25.fc21.x86_64).
This looks similar to https://sourceware.org/bugzilla/show_bug.cgi?id=17408

I'm hitting this on Fedora 21 with gdb-7.8.2-38.fc21.x86_64 and binutils-2.24-30.fc21.x86_64 when debugging with insight-7.8.50-4.20140827git.fc21.x86_64.

Maybe it's because insight is "older" than the fix?
The failed assertion doesn't seem to happen in commandline gdb.

Comment 5 Jan Kratochvil 2015-05-20 06:40:14 UTC

'insight' contains its own build of GDB so file that for Component 'insight'.
