possible memory leak

[BreakElseHalt]

Hi,

we get some errors working on a specific .int file.
Looks like this was already reported and fixed with #351.
I've updated to InterSystems Language Server 2.7.0 but unfortunately the error still occurs.
Can be reproduced.

Hi @BreakElseHalt, thanks for reporting this. Can you send me the file that you're seeing the leak on? If you're not comfortable sharing this publicly, you can send me a direct message on the Developer Community. Does the crash occur when you open the affected file, or after editing it for some time?

Hi @isc-bsaviano, please excuse my late response, unfortunately I cannot provide this specific file but I'm working on a similar one to mock the behaviour.
The crash occurs while editing.
Thanks!

No worries @BreakElseHalt, I appreciate you reporting this and helping me reproduce it!
