代码：
static char * (*orig_getenv)(const char *name);
char *my_getenv(const char *name) {
NSLog(@“my_getenv invoked:%s”,name);
return orig_getenv(name);
}
%ctor{
struct rebinding binds[1];
struct rebinding binds_1 = {“getenv”, (void *)my_getenv, (void **)&orig_getenv};
binds[0] = binds_1;
rebind_symbols(binds, 1);
}问题：
我用nslog输出调用的情况，结果只是一个app调用次数，日志输出了上万条日志，造成app卡死的情况，求指教问题出在哪里？还是说是正常情况？日志(截取一部分)：
