Probably-leaking memory around coroutines debug instrumenter

[mglukhikh]

Reproduction: in Kotlin project, run FirDiagnosticsSpecTestGenerated using Gradle from IDEA interface (not from command line). After ~40% tests passed, you will first see slowdown and then tests begin to fail with "GC overhead limit exceeded". NB: when run from command line, tests are completed without problems. NB2: tests can be run one-by-one also without problems.

In memory snapshot I see that a lot of FirCompisiteSymbolProviders are hold by statics or constant pool of kotlinx.coroutines.debug.internal.DebugProbesImpl. Looks like it points to some coroutine debug instrumenter problem.

Looks like duplicate for #2117

It is fixed in kotlinx.coroutines version 1.3.8. Which version you observe this problem on?

[mglukhikh]

1.3.7.
