Bug ID: 387294
Summary: Crash in KDevelop::OutputExecuteJob
Product: kdevelop
Version: git master
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: fa...@kde.org
Target Milestone: ---
1) KDevelop::OutputExecuteJob: maybe doKill should disconnect
childProcessStdout?
2) shutdownGracefully leads to a complete lockup when the malloc mutex is
held...
