Thanks for these replies...
jens: I disabled the CodeCompletion plugin, exited C::B, restarted C::B and opened the workspaces without any issues. Thanks, that saved my day. Apparently there is something fishy in the CodeCompletion plugin that causes the crash. If I re-enable the CC plugin and restart C::B again, the crashes return.
MortenMacFly: Be aware that my setup is a little special, perhaps it is of some relevance?
All my projects have 4 build targets
GCC_Release (currently used on linux only)
GCC_Debug (currently used on linux only)
MSVC_Release (used on Windows only)
MSVC_Debug (used on Windows only)
I am using Bazaar source control (on Windows only). For linux development, I syncronise source and project files over Samba, using
Komparator, then edit as required, compile&link. When happy, I use Komparator to sync it back over Samba, then commit to Bazaar there.
If, for some reason, the CC plugin tries to access the MSVC compiler on linux, it certainly will not succeed. If that is the issue, it should just give up, but not crash.
