When I compile my code with a sanitizer, and set `ASAN_OPTIONS=log_path=/tmp/file.log,symbolize=0`, the resulting log file looks like this:
```
==1429==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 72 byte(s) in 1 object(s) allocated from:
#0 0x56387d58b50f (/usr/bin/daemon+0x11f50f)

#9 0x7f965d32b03c (/lib64/libc.so.6+0x2403c)
```
When I set `symbolize=1`, the stack traces have line number and function info, but that `daemon` program actively manipulates its children, so when `llvm-symbolizer` becomes its child, it misbehaves.
Nevertheless, I can symbolize this output by running `llvm-symbolizer /usr/bin/daemon 0x15d0bb`, but it's annoying to do it manually for each line.
May I ask that a standard filter be added, so that I could just run: `llvm-symbolizer /tmp/file.log > file.symbolized.log`?
