If you can send an example I can use to reproduce this, I'd appreciate it. It's going to be difficult to investigate without one.

I was investigating some app using valgrind. It spawned bash, and occasionely some leaks were detected in bash. It is Fedora 30, bash is pretty recent, i.e. 5.0, please have a look at findings

```

diag 0.0 ==13498== 2 bytes in 1 blocks are still reachable in loss record 17 of 899^M
