New description:
Currently, the exceptions thrown by PARI are rather cryptic, like
{{{
Traceback (most recent call last):
...
PariError: (15)
}}}
This ticket does the following:
- Use {{{cb_pari_handle_exception()}}} instead of {{{err_catch()}}} to
catch PARI exceptions.
- Using a mechanism similar to #9636, catch the full text of the exception
and pass it to {{{PariError}}}.
- Introduce a new function `sig_error()` to callback to the
interrupt/signal handling code to handle errors which aren't signals and
use that for PARI.
