Computing class inheritance relations → segmentation fault when run against vulkan-hpp headers

[triffid]

Describe the bug
Doxygen segfaults when run against the contents of https://github.com/KhronosGroup/Vulkan-Hpp/tree/main/vulkan/ at "Computing class inheritance relations…"

To Reproduce

1. clone https://github.com/KhronosGroup/Vulkan-Hpp
2. cd Vulkan-Hpp/vulkan
3. generate a basic doxyfile for C++ - I just used doxywizard, changed basically nothing, and hit save
4. run doxygen

Expected behavior
Generates html describing the headers, or at least prints a normal error if there's a problem

Version
doxygen 1.9.8

Gentoo Linux x86_64 (doxygen compiled locally using Gentoo's ebuild)

Additional context
I just want some proper documentation for Vulkan-hpp's class hierarchy; apparently none exists anywhere - available documentation basically just says "we basically copied the C library and changed stuff around, good luck"

[albert-github]

I did a quick test with the current master version of doxygen under Cygwin (1.12.0 (b3c28ea)) and got also a crash with an default Doxyfile.

As the provided example (master version of Vulkan-Hpp) is not persistent I added the used code as example:
Example: example.tar.gz

[albert-github]

I reduced the problem significantly to: example1.tar.gz

The place of the crash looks like a different place than the initial mentioned place, so maybe there are even multiple problems ( :-( )

[doxygen]

@triffid Please verify if the referenced commit fixes the problem for you. Do not close the issue, this will be done automatically when the next official release becomes available.

[doxygen]

This issue was previously marked 'fixed but not released',
which means it should be fixed in doxygen version 1.12.0.
Please verify if this is indeed the case. Reopen the
issue if you think it is not fixed and please include any additional information
that you think can be relevant (preferably in the form of a self-contained example).
