Comment(by leif):
I actually added some more {{{printf()}}}s:
{{{
#!C
...
fprintf(stderr,
"\n******************** PARI ERROR: ********************\n");
vfprintf(stderr,fmt,ap2);
fprintf(stderr,
"\n*****************************************************\n");
fflush(stderr);
...
}}}
Of course a temporary hack (and a bit odd in the interpreter), but an
improvement to just
{{{
File "gen.pyx", line 9460, in sage.libs.pari.gen._pari_trap
(sage/libs/pari/gen.c:45047)
PariError: (5)
}}}
and trivial enough s.t. it could be merged without any risk. ;-)
(PARI's messages of course aren't always that informative without
examining the stack.)
