Bug ID: 511347
Summary: Enormous memory usage on big numbers in calculator
Classification: Plasma
Product: krunner
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: calculator
Assignee: [email protected]

Target Milestone: ---
SUMMARY
Calculation which results in very big numbers use an insane amount of ram. Ram
doesn't free up unless krunner is killed.
STEPS TO REPRODUCE
1. Enter the following calculation
`99999999999999999999999*99999999999999999999999*99999999999999999999999*99999999999999999999999*99999999999999999999999*99999999999999999999999*99999999999999999999999`
OBSERVED RESULT
Ram usage by krunner increases to 500MB.
Ram doesn't free up until krunner is killed.
Increasing the calculation increases ram usage exponentially (reached 22GB on
my system by copy pasting the above calculation multiple times)
EXPECTED RESULT
Drastically lower ram usage
