Follow-up Comment #48, bug #53841 (project octave):

When I delete the qch and qhc files and try to let flatpak-build regenerate
them using qhelpgenerator 5.12, it fails in the build with a segfault:

rm -f doc/interpreter/octave_interpreter.qhc
doc/interpreter/octave_interpreter.qch && \
perl ./doc/interpreter/mk-qthelp.pl octave.html
doc/interpreter/octave_interpreter && \
qhelpgenerator  doc/interpreter/octave_interpreter.qhcp -o
doc/interpreter/octave_interpreter.qhc >/dev/null && \
rm -f doc/interpreter/octave_interpreter.qhcp
/bin/sh: line 3: 17171 Segmentation fault      qhelpgenerator
doc/interpreter/octave_interpreter.qhcp -o
doc/interpreter/octave_interpreter.qhc > /dev/null

Not very encouraging. Note that this is also with
QCOLLECTIONGENERATOR=qhelpgenerator, because the two tools were merged in Qt

And yeah, I'm not dismissing mxe-octave, I know that it's not feasible to
build both native and cross versions of Qt just to be able to build the help
files with the same version of Qt. I just wanted to test to see whether
building the help with the same version of Qt would resolve this, and I can't
even test that.
