musl - an implementation of the standard library for Linux-based systems

if async cancellation is enabled and acted upon, the stack pointer is
not necessarily pointing to a __syscall_cp_asm stack frame. the
contents of the stack being wrong don't really matter, but if the
stack pointer is not suitably aligned, the procedure call ABI is
violated when calling back into C code via __cancel, and pthread_exit,
cancellation cleanup handlers, TSD destructors, etc. may malfunction
or crash.
for the async cancel case, just call __cancel directly like we did

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
