Thanks for your analysis. I can confirm your findings.

That would be a binNMU,[0] but:

I've uploaded 0.18-4 (with a versioned build dependency on
libgumbo-dev) with some packaging updates to unstable which should
fix the current issue.

What is not beautiful is that the generated runtime dependency is
still "libgumbo2 (>= 0.12.3)". There seems to be some undocumented
API/ABI compatibility problem.


For the future: When a prepare a new release of gumbo-parser you
could test reverse dependencies and/or upload to experimental as a
first step.


Cheers,
gregor
