There are issues with the test attaching to the debuggee too soon, and the debug agent isn't ready. yet. This test is based on ProcessAttachTest, which does not have this issue. I eventually realized the reason why is because ProcessAttachTest has this little snippet of code, which I had removed from DataDumpTest:
This is waiting for the start of the debug agent's "Listening..." message. I've re-added this to DataDumpTest, and it seems to fix the issue. Tested by running 20 times with
-Xcomp
on all supported platforms with no failures. It used to fail about 2/3 of the time.Progress
