annotate src/number-mp.h @ 5489:159face738c3
Never pass a leading + to mpz_set_string, parse_integer ().
src/ChangeLog addition:
2011-05-01 Aidan Kehoe <kehoea@parhasard.net>
* lread.c (parse_integer):
GMP's mpz_set_string deals with a leading plus badly, make sure it
never sees one coming from this function.
tests/ChangeLog addition:
2011-05-01 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-reader-tests.el:
If the bignum feature is available, check that a leading plus sign
is treated correctly when reading bignum integers.
