Hello,
I'm experiencing some crashes when running unit tests for Chromium browser. I
wonder if you've ever seen anything similar. Any advice on how I can debug that
would be appreciated!
1) I'm running "unit_tests" binary built with coverage instrumentation:
$ ./unit_tests --test-launcher-jobs=1 --single-process-tests

2) I'm trying to run the test individually, it works fine:
$ unit_tests --test-launcher-jobs=1 --single-process-tests
--gtest_filter=*ProfileManagerTest.LoadExistingProfile*
Note: Google Test filter = *ProfileManagerTest.LoadExistingProfile*

3) I'm trying to run a subset of tests, it also works fine:

--gtest_filter=*ProfileManagerTest*
Note: Google Test filter = *ProfileManagerTest*

4) I'm trying to run the whole thing under GDB, it crashes, but with different
stacktrace:

It feels like our tests can be doing some weird things, but still have no clue
