Public bug reported:
I'm using ubuntu 15.04
I'm trying to use the "leak sanitizer" feature of address sanitizer in stand
alone.
Here is the a simple code example:
#include <stdlib.h>
int main(){
malloc(1);
return 0;
}
Compiled with gcc-4.9 -g -fsanitize=leak and running the program, I observe no
output, and the binary does not link to /usr/lib64/liblsan.so while it should.
With clang or the gcc-5 of ubuntu 15.04 (5.1.1) it works fine, I have the
expected output:
=================================================================
==7779==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 1 byte(s) in 1 object(s) allocated from:
#0 0x7f3d7f94f9a5 in __interceptor_malloc
(/usr/lib/x86_64-linux-gnu/liblsan.so.0+0xc9a5)
#1 0x4006b3 in main /home/tellaa/dev/clang_test/main.cpp:4
#2 0x7f3d7f599a3f in __libc_start_main
(/lib/x86_64-linux-gnu/libc.so.6+0x20a3f)
SUMMARY: LeakSanitizer: 1 byte(s) leaked in 1 allocation(s).
For the record:
-the gcc of ubuntu 15.10 (gcc-5.2.1) does not work either.
- I compiled gcc from source, and it worked
