And the problem is that regexplorer is licensed under the plain QPL?

As far as I know, Debian complies with the QPL requirements, so we can
choose between QPL and GPL on a per-application basis.

Yes, as long as you use GCC to compile regexplorer.

It's dual-licensed.

No, all source files should be covered by the usual exception. If
they aren't, upstream considers this a bug.

QPL is usually considered free, but its use is discouraged. An
additional exception, as granted by OCaml for example, can improve
things.
