Version 4.7.2, Fedora Linux (x86_64) release 4.1.8-100.fc21.x86_64 This was originally reported in Bug 355094; it was requested I open this as a separate issue. I have a large, mostly C, project. When I move the cursor on to the word "bool" or "true" or "false", even if the mouse ust passes over it, KDevelop will hang, consuming CPU. This is old code, and likely there are multiple definitions of these types/values within the project. It does not matter the context of the usage: as the type of a function definition ("bool fn() {}"); as a literal in assignment ("var = true;"); etc. This appears to be a regression from 4.7.1 to 4.7.2, as this just started happening with the upgrade to 4.7.2. Reproducible: Always Steps to Reproduce: In a C module, move the cursor or mouse over a word with many usages (and possibly multiple definitions), such as "bool" or "true". Actual Results: KDevelop will hang, consuming 100% of a CPU core. Expected Results: Context pop-up; not hang.
