in cases where rounding caused a carry, the slot into which the carry was taking place was unconditionally treated as valid, despite the possibility that it could be a new slot prior to the beginning of the existing non-rounded number. in theory this could lead to unbounded runaway carry, but in order for that to happen, the whole uninitialized buffer would need to have been pre-filled with 32-bit integer values greater than or equal to 999999999. patch based on proposed fix by Morten Welinder, who also discovered and reported the bug.
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.0 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
