<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">1) No need for the cast
2) I believe the trendy way to do this now is to call ast_std_calloc() instead of calloc().</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There is nothing trendy about it. If you think you are using the standard library allocation routines by calling plain calloc() you will most likely be wrong. The standard allocation routines get redirected by the C preprocessor to the allocation routines in astmm.c by MALLOC_DEBUG.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch corrects a consistency issue with debug threads that I
noticed while fixing ASTERISK-22455.
The initialization of a mutex's lock tracking structure was not
protected in a critical section. This is fine for any mutex that is
explicitly initialized, but a static mutex may have its lock tracking
double-initialized if multiple threads attempt the first lock
simultaneously.
This patch creates a global mutex to properly serialize the
initialization of the lock tracking structure for a mutex. It also
changes lock.c to properly handle allocation failures of the lock
tracking structure.</pre>
