Precompilation error with ParserCombinator

[abelsiqueira]

I have the following error when adding GraphIO and ParserCombinator in a brand new Julia session:

Warning: Module GraphIOGMLExt with build ID ffffffff-ffff-ffff-0000-177dba44e6bc is missing from the cache.
│  │ This may mean GraphIOGMLExt [10735248-2040-59e9-9abe-fdd6b710d968] does not support precompilation but is imported by a module that does.
│  └ @ Base loading.jl:1793
│  ┌ Error: Error during loading of extension GraphIOGMLExt of GraphIO, use `Base.retry_load_extensions()` to retry.
...

And a similar error for GraphIODOTExt.

I have not been able to identify where the issue comes from, but I am opening the issue here since the error only happens if I add both packages and the extension is defined here. However, it doesn't seem to be an error exclusive to this package, so I will open a discourse thread as well.
