Thanks for testing this.

You could do "gdb perl core" with the core file, and give the "bt" 
command to gdb to get a stack trace.  This should show where in the 
extension modules something is going wrong.  If there are no debugging 
symbols, then you would have to run "configure" again with 
PERL_EXT_CFLAGS containing -g.

Is it possible for you to send the contents of 
the file 
tp/tests/nested_formats//out_parser/texi_nested_formats/nested_formats.2 ?
(This is possibly just the message saying that there was a seg fault.)

You could also export TEXINFO_XS=debug and run one of the test scripts, 
e.g. test_scripts/nested_formats_texi_nested_formats.sh from within the 
tp/tests directory.  (This is easier to do if you configured in-source: 
otherwise you have set a whole load of environment variables for this to 
work.)  This will definitely lead to a failed test but there might be 
useful information in nested_formats//diffs/texi_nested_formats.diff or
nested_formats//out_parser/texi_nested_formats/nested_formats.2, e.g.:
