Notes: - Repro rate seems to be 100% when running the full suite, but which tests end up stuck seems random. In particular, these are not failing tests. - We may well manage to *start* running every test, but then we just sit at the end forever since some number of subprocesses will never terminate. - Running a subset of tests with --filter is generally stable, and it seems that even --quick usually terminates successfully. 1475330 1 ross.kirsling 2018-11-05 16:28:10 -0800 As mentioned in the previous ticket, the stack trace for all hanging subprocesses is: > [External Code] > jscLib.dll!`anonymous namespace'::jscExit(int status) at Source\JavaScriptCore\jsc.cpp(174) > jscLib.dll!main(int argc, char * * argv) at Source\JavaScriptCore\jsc.cpp(2275) > jscLib.dll!dllLauncherEntryPoint(int argc, const char * * argv) at Source\JavaScriptCore\jsc.cpp(2855) > jsc.exe!main(int argc, const char * * argv) at Source\JavaScriptCore\shell\DLLLauncherMain.cpp(222) > [External Code] Attaching to process and hitting the Pause button breaks at jsc.cpp:174, and attempting to Step Into has the same effect as hitting Continue, since the call stack above the `exit(0);` call is just "external code". 1475371 2 ross.kirsling 2018-11-05 18:48:51 -0800 Hmm, it seems like if I ensure that we never collect continuously, then none of the subprocesses hang!
