[Nagios-devel] Compiler warnings

Post by Guest »

Ahoy.

I was digging around trying to fix a bunch of compiler-warnings, and
noticed that pretty much every invocation of my_free() resulted in
about a million warnings, such as this:

../xdata/xrddefault.c:190: warning: dereferencing type-punned
pointer will break strict-aliasing rules


Considering that not a single invocation of my_free() evaluates the
return code of the function, a macro such as

#define my_free(ptr) { if(ptr) { free(ptr); ptr = NULL; } }

would do the trick, and also provide a slight performance improvement.

Since a patch would be fairly huge, and I've kinda filled my quota
for huge patches for today, the following sed-script will take care
of the call-sites (requires sed 4.0.9 or later):

sed -i 's/my_free[^&]*&\([^)]*\).*/my_free(\1);/' */*.c
