Re: 1.3.20 most recent upgrades : rxvt creates 100% load on CPU


Here is the output from strace for rxvt on my system. It is a short 
but it is repeated indefinitely.

It seems that the attachment it is in Unix format, it was generated under

First off, please *attach* your cygcheck output as an uncompressed text,
as per <>.  The presense of all the packages in
the cygcheck output in the body of the message creates false positives
when people try searching the archives, which results in more "archives
are useless" posts.  If you did send yours as an attachment, check your
mail software configuration, it's likely set to put text attachments

That said, try attaching to the hanging/100% CPU rxvt process with
"strace" (I'm assuming Task Manager shows rxvt as using 100% CPU).  See
where it's hanging.  You might also try "gdb", but that's likely to help
less.  Snip out the relevant strace output and post it to the list (as an
attachment, probably compressed, as it's likely to be large).  At least
it should give you an idea of where it's looping.  If strace doesn't
produce any results (i.e., rxvt hangs/loops inside a Windows DLL
somewhere), try running "strace -o rxvt.strace rxvt <youroptions>" and
look at the bottom of that output.  For more details, "strace --help".
