One long test failed in

devel/sage/sage/modular/modform/find_generators.py

I ran it with the verbose option and got (only the relevant part is listed):

------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred because a *compiled* component of Sage has a bug
in it and is not properly wrapped with sig_on(), sig_off(). You might
want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate.
------------------------------------------------------------------------
The doctested process was killed by signal 11
         [12.4 s]

As fate would have it, this is precisely one of the corners of the
Sage code base that I'm most interested in...
