Comment(by plobsing):
Replying to [ticket:1610 dukeleto]:
> Parrot_compile_string is supposed to fill an error_string with error
messages, which it does in certain cases, but if an IMCC syntax error
occurs, the exception bubbles up out of Parrot_compile_string. This
currently causes PL/Parrot to coredump PostgreSQL for stored procedures
that have incorrect syntax.
>
> chromatic++ suggested installing a C exception handler with
Parrot_ex_add_c_handler into Parrot_compile_string, but I have not been
able to get it to work yet.
Here's a patch that fixes this issue slightly by changing IMCC's yyerror
to not fprintf(stderr,...).
It changes the format of error messages slightly, causing some tests to
fail.
