27.0.50; Assertion failure for dot-terminated large int |
|
Date: |
Sun, 19 Aug 2018 18:50:57 -0400 |
Package: Emacs
Version: 27.0.50
With the nw bignum code in Emacs master, reading a large integer with
trailing dot triggers an assertion failure:
M-: 4294967295. RET
for me triggers the problem (seen in elpa/packages/xelb/xcb-types.el).
I suspect on a 64bit host you'll need:
M-: 18446744073709551615. RET
to trigger the same bug (the integer needs to be large enough not to
fit in a Lisp fixnum but small enough to fit in a uintmax_t).
The assertion that fails is the `eassert (check == 0)`
in alloc.c:make_bignum_str.
BTW, I was surprised to discover that until now "42." was read as the
*integer* of value 42 rather than the float of that value. I guess
we're stuck with this behavior but I find it odd.
