[PULL 10/10] util/compatfd.c: Replaced a malloc call with g_malloc.
Posted by Thomas Huth 4 years, 9 months ago
From: Mahmoud Mandour <ma.mandourr@gmail.com>

Replaced a call to malloc() and its respective call to free()
with g_malloc() and g_free().

g_malloc() is preferred more than g_try_* functions, which
return NULL on error, when the size of the requested
allocation  is small. This is because allocating few
bytes should not be a problem in a healthy system.
Otherwise, the system is already in a critical state.

Subsequently, removed NULL-checking after g_malloc().
