Yes, you are probably right about the wrong 'free' being used.

The function called at that line in LaTeX.pm is index_element_sort_string
in tta/C/main/manipulate_indices.c.  But I don't know which "free" call
would be responsible under that function or why the Perl malloc would
have been used.

I think it's likely the XS modules were used in your test run.  I think
it's a good idea to report at the start of the output whether XS modules
are enabled.
