I occasionally get test failures in the
"perl -w t/03coverage_braces.t definfoenclose_texinfo_commands" test,
but cannot usually repeat it reliably. I suspect some issue with memory
corruption or issue with uninitialised memory, although I've not managed
to get anything to show up with valgrind so far.
To get it to fail, I need to do
"while perl -w t/03coverage_braces.t ; do true ; done"
and then wait a while.
Here is the result of
"diff t/results/coverage_braces/definfoenclose_texinfo_commands.pl*"
on one of the occasions I was able to get it to fail after running
"TEXINFO_XS=require perl -w t/03coverage_braces.t".
The code was changed recently (2024-02-18, commit b447793774).

On another occasion, the diff was different:
