Comment (by SimonKing):
Thanks to Volker's enhanced backtraces, running the test in verbose mode
and without gdb yields [attachment:sage_crash_WgD9iG.log this backtrace],
and the crash occurs here (line 6467 of heegner.py)
{{{
sage: E = EllipticCurve('681b')
sage: I = E.heegner_index(-8); I
}}}
Unfortunately, running this in an interactive session works just fine.
