No problems encountered.

Yes it does.

$ cygcheck -c texinfo
Cygwin Package Information
Package              Version        Status
texinfo              4.2-4          OK

No crash.

It's definitely our friend textutils. Examining the output from the zcat
piped through less shows that second and subsequent lines begin "^@",
which is the likely cause of the problem. Removing the nulls allows
"cygcheck -cv" to succeed.

Thank you very much for your help in locating the source of the problem.

Cheers
