perf tools: Fix build error due to zfree() cast
It failed to build perf on my ubuntu 10.04 box (gcc 4.4.3): CC util/strlist.o cc1: warnings being treated as errors util/strlist.c: In function ‘str_node__delete’: util/strlist.c:42: error: dereferencing type-punned pointer will break strict-aliasing rules util/strlist.c:42: error: dereferencing type-punned pointer will break strict-aliasing rules CC util/strfilter.o make: *** [util/strlist.o] Error 1 CC util/srcline.o cc1: warnings being treated as errors util/srcline.c: In function ‘addr2line_init’: util/srcline.c:132: error: dereferencing type-punned pointer will break strict-aliasing rules util/srcline.c:132: error: dereferencing type-punned pointer will break strict-aliasing rules util/srcline.c: In function ‘addr2line_cleanup’: util/srcline.c:143: error: dereferencing type-punned pointer will break strict-aliasing rules util/srcline.c:143: error: dereferencing type-punned pointer will break strict-aliasing rules make: *** [util/srcline.o] Error 1 It seems it only allows to remove 'const' qualifier.
