tangzhiqiang3 opened a new issue, #2383:
URL: https://github.com/apache/brpc/issues/2383
demo program：
`#include <stdio.h>
#include <gperftools/tcmalloc.h>
int main()
{
char *ptr = (char *)tc_malloc(sizeof(char));
if(ptr){
printf("tcmalloc works failed!\n");
}
tc_free(ptr);
printf("tcmalloc works fine.\n");
return 0;
}`
