test/task.scm failure: "return pointer from a task run in thread" apparent PASS but actually crash the test suite

[Jehan]

When running make test, it fails when in task.scm:

PASS: test/task.scm - return pointer from a task run in thread

The file task.log (attached) doesn't give much information other than the fact it seems to crash after outputting the contents of the ""cancel task and check cancellable"" test. If I remove this test, it fails on every next one, and even if I remove all the last test (just keeping (test-end "task") in the end), it still crashes.

Actually it turns out that the real culprit is the last to pass: "return pointer from a task run in thread". If I only remove this test, the whole test suite passes.

Hmm, could it be, that some process is not cleaned up correctly? Try displaying the current process ID before and after "return pointer from task run in thread". If they're equal, everything should fine. If they're not, or the latter display is executed twice, we have an error.
