Description Maciej Cencora 2020-02-26 13:20:49 UTC 
SUMMARY
During parsing of entire medium-sized projects (~8K source and header files) KDevelop process increases its RSS memory usage from ~300MBs to ~10GBs.

STEPS TO REPRODUCE
1. Open not yet parsed project
3. Watch memory usage in "System Monitor"

OBSERVED RESULT
Memory usage constantly increases during background parsing of every TU. Memory is freed only after ~1 minute after the background parsing of whole project is finished.

EXPECTED RESULT
Memory used during background parsing of given TU should be released almost immediately after parsing of given TU is done, not after parsing of whole project is finished.
