Doesn't work: the 'perl' program and the 'core' file have no debugging
information.

$ gdb /usr/bin/perl core
...
GNU gdb (GDB) 7.10

Rebuilt with cc (like last time), and with PERL_EXT_CFLAGS="-g". The result:

1) In the tp/tests/ directory: a 'core' file again and 20 test failures.
"gdb /usr/bin/perl core" doesn't produce usable information either.
2) In the info/ directory, 2 tests fail. Find the log file attached.

Rebuilt with gcc instead of cc, and with PERL_EXT_CFLAGS="-g". The result:
1) In the tp/tests/ directory, no 'core' file any more, all tests succeed.
2) In the info/ directory, 2 tests fail. Find the log file attached.

This file is empty.

The Makefile sets the environment variables for me:
$ TEXINFO_XS=debug gmake check 
TESTS=test_scripts/nested_formats_texi_nested_formats.sh
This run produces a couple of files, which you find attached, and a 'core' file,
which is too large to attach.
