We are also seeing a failure in this test due to a similar reason as the strcpy-overlap.cpp test:
```
#0 0x55e55ffaf717 in cfree.part.0 /home/jenkins/compiler-rt/lib/asan/asan_malloc_linux.cpp:52:3
```
Note the name `cfree.part.0` which does not have the expected space after it which your change is expecting.
