Hmm that's something new. It "works" with xterm, however there is no
information in memproof's main window.
At least it doesn't hnag-up. This seems to be #349295
Normally I was trying to memproof my own application, which was working with
memproof. but it was long time ago (May/Jun 2005)
Right now this app hangs memproof.
I noticed one more thing: When I was trying to run
$ memproof /usr/bin/xterm
(as a normal user) I had this error message:
** (memprof:2989): WARNING **: Can't open /proc/2990/mem
this "file" was readable only by root, so I made the same thing as root
# memproof /usr/bin/xterm
There was no error message, and main window of memproff was empty.
If memproof is using data from /proc/* maybe there was some change in the way
all this data is sored here?
if I do
# cat /proc/<some running PID>/mem
There is empty file.
