--- Re-run this test:
python3 tools/test.py -n dartkp-tsan-linux-release-x64 vm/dart_2/regress_45898_test

[a-siva]

Should this test be marked as slow under TSAN also? The current status file marks it as slow for
$compiler == dartkp && ($arch == simarm || $arch == simarm64 || $arch == simarm64c)

It seems to generate an example that causes generattion of type testing stubs for 10000 classes.

The stack trace above doesn't show any kind of hang situation the compiler seems to be compiling stuff and maybe it just takes longer.
