Sometimes calling GC.collect() results in Memory.cpp:987: runtime assert: Must be positive

[Dominaezzz]

Haha fun. Do you have a reproducer?

[Sam Schilling]

Trying to rip out the code that’s doing it reliably atm

[Dominaezzz]

Sweet

[Sam Schilling]

The code is rather involved and there’s a lot of different pieces going on (multithreading Mac application that interfaces with K/N framework) and the failure is inconsistent so it’s hard to pin down

[Sam Schilling]

My application is processing network requests and it typically throws that error within a few requests but sometimes it’s the 1st, sometimes the 4th etc

this is likely symptom of memory corruption due to incorrect concurrency, and we recently improved it with 215cf054106a2c8610f094227e69f1cbc78bdf29 and friends, so better try with dev snapshot before deep investigation.

[Sam Schilling]

Good to hear. What do you mean by incorrect concurrency?

[Sam Schilling]

And do you have info on how to use a dev snapshot with gradle?
