Hi!
I'm working on #715, #12215 and #11521, which are supposed to use weak
references, in order to make unused parent structures and coerce maps
garbage collectible.
The good news is that with #715, all tests pass. The bad news is that
with either of the two other tickets, some tests in sage/schemes/
elliptic_curves/ receive signal 11.
The problem is that I have no clue how these crashes could be
analysed. Namely, when I run the tests with -verbose, then apparently
all tests pass, and only in the very end the crash occurs, such as:
660 tests in 73 items.
660 passed and 0 failed.
Test passed.
The doctested process was killed by signal 11
[15.1 s]
Apparently no doctest crashes, but the test engine crashes.
What is worse: When I run it with -verbose -randorder, there is no
crash at all, most of the time.
What tool/technique would you recommend for debugging it?
Best regards,
Simon
