Problems running kdevelop in valgrind/callgrind

[Andreas Pakulat]

Hi,

wanted to run callgrind on kdevelop to check whats making cmake project
opening slow. But it seems to be impossible as kdevelop crashes as
soon as I open a project with valgrind/callgrind running on it.

The backtrace I get from the callgrind process indicates a problem with
the DUChain usage in CMake, this also fits with the reproduceable crash
when editing a CMakeLists.txt file and saving it inside kdevelop4 (also
crashes in the duchain and the backtrace seems to be pretty similar to
the one I have)

Backtrace from valgrind:
