the plural_rule field of allocated msgcat structures was assumed to be initially-null but was never initialized. for future-proofing, the nplurals field which was left uninitialized should also be cleared. likewise, in the binding structure, the active field could be used uninitialized by a technicality: the a_store which stores the initial value of 0 may be implemented as a cas operation, which reads the old value. rather than fixing these issues individually, just use calloc for both allocations. this does result in wasteful clearing of name buffers (up to NAME_MAX+PATH_MAX) before filling them, but since the size if bounded and the time is dominated by filesystem operations, it really doesn't matter; simplicity and future-proofing have more value here. modified from patch submitted by He X.
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 1.1 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
the project website:
