Comment:
Email from Bill Allombert in response to the bug:
{{{
Hello,
This problem does not occurs with PARI 2.4.3.
This seems to be another instance of bug #505 which was fixed in
PARI 2.4.1 as
1- qflll / qflllgram (t_MAT with t_FRAC entries) would not reduce to
the integer case (--> insufficient precision, SEGV) [#505]
The fix should probably be backported.
Thanks for your bug report,
Bill
