From: <chenggang....@taobao.com> While I compile the perf in Red Hat Enterprise Linux Server release 5.4 (Tikanga), I got a warning:
CC util/trace-event-parse.o cc1: warnings being treated as errors util/trace-event-parse.c: In function 'parse_proc_kallsyms': util/trace-event-parse.c:232: warning: 'fmt' may be used uninitialized in this function make: *** [util/trace-event-parse.o] Error 1 The version of gcc is: 4.1.2 The reason is that the local variable 'fmt' is not initialized before we use it. It is fixed in this patch.
