Rich Felker 50cd02386b fix invalid-/double-/use-after-free in new dlopen ctor execution 
this affected the error path where dlopen successfully found and
loaded the requested dso and all its dependencies, but failed to
resolve one or more relocations, causing the operation to fail after
storage for the ctor queue was allocated.

commit 188759bbee wrongly put the free
for the ctor_queue array in the error path inside a loop over each
loaded dso that needed to be backed-out, rather than just doing it
once. in addition, the exit path also observed the ctor_queue pointer
still being nonzero, and would attempt to call ctors on the backed-out
dsos unless the double-free crashed the process first.

    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:
