This race will always happen sooner or later in a multi-threaded

This fix works by spinning, there are other ways by which this
can be fixed, like simply detecting the issue after it happened

The check `src > dst' in the form `&c->out[-back] > c->out' invokes

The escape API will be useful to perform escaping programmatically, which

On recent android versions, /proc/self/auxw is unreadable
(unless the process is running running under the shell uid or
in debuggable mode, which makes it hard to notice). See
http://b.android.com/43055 and
https://android-review.googlesource.com/51271 for more information
about the issue.
This makes sure e.g. neon optimizations are enabled at runtime in
android apps even when built in release mode, if configured to
use the runtime detection.

Memory passed to av_realloc must come from malloc,
calloc or realloc, and not e.g. memalign. realloc(3):
The realloc() function changes the size of the memory block pointed to
by ptr to size bytes. (...) Unless ptr is NULL, it must have been
returned by an earlier call to malloc(), calloc() or realloc().
The issue has been found by debugallocation, a part of google-perftools:
http://code.google.com/p/gperftools/ .
This makes fate pass when using LD_PRELOAD-ed debugallocation.
