Niels,
That seems to have fixed the memory leak, thanks. Making it through
further in the compilation process, though, we start to hit more
undefined references with the sanitizers turned on with clang16:
```
clang -fsanitize=address -fsanitize=leak -g -O2 -ggdb3 -Wall -W
-Wno-sign-compare -Wmi

Thanks for
Niels,
Any thoughts on this? Since this runs as part of the build process, it
is blocking one of our pipelines.

If it looks like the sanitizer could be right, can you share the error
report?

This indeed did the trick. It's still a bit mysterious why older
versions of clang didn't have this pr
