malloc and free, apparently, given that the right header files have
been included:


No Perl header files are included in text.c. The only place in the
source I can see where this could cause a problem is around line 877
of xspara.c, here:

 free (new_space.text);

in xspara_add_text. Is the crash still coming from
XS_Texinfo__Convert__XSParagraph__XSParagraph_new? If so I don't
understand it because there should be no free-ing there after the
patch I posted.

I think a simple way to remove the problem, in the call to free here
at least, is to add a function to text.c which can be called instead
to avoid using Perl's version of free.
