Thanks, Ken for the following info:
This looks like a bug I reported several years ago; it actually has
nothing to do with emacs:
It was fixed but then reappeared some months later:
It was fixed again but apparently is back. The test case from the
original report still exhibits the problem.
I had a look at the elisp-function gdb-send.
The command process-send-string is used there for sending commands to gdb.
Is it right that the problem manifests itself already there?
The doc of process-send-string says that this command may send the string
contents as separate bunches of data.
If the output is already incomplete because of the partitioned input through
process-send-string I see no way for a cygwin-specific workaround and we must
wait for a fix of gdb.
I already wrote a test case (which was improved by cgf) in my original
bug report. As you can see from reading that old thread, the problem
*is* Cygwin specific and is provoked without partitioned input.
Do you know where I should report the bug?
This email thread is the right place to report the bug.
