Hello,
the entries for terminals "cygwin" and "linux" in /etc/termcap seem to
be larger than
1024 bytes. compile the following program with the command line
gcc -o tgettest.exe tgettest.c -ltermcap
and run it with
tgettest linux
You will see that the length of the returned Buffer is larger than 1024
bytes. In the second
call a different Buffer (Buffer2) gets overwritten.

A personal remark:
Since according to the ChangeLog file for termcap I concluded that
Christopher Faylor is
maintaining termcap, I CCed him my second message and obtained a quite
insulting response.
I have spent several hours to locate this bug and wouldn't have expected
that kind of response
even from Bill Gates himself, who thinks that there are no errors in his
programs and all problems are caused by silly users. Certainly I
wouldn't expect this answer from any contributor to Open Source!
Usually the program maintainers prefer to have errors reported directly
to them and not to the
public, so they can react promptly.
In fact, this is the first insulting response from this direction.
I append the required cygcheck output
