xscreensaver drawing debugging messages on lock window

xscreensaver-4.05-1 from rawhide.
I've got xscreensver configured to just blank the screen. When I go to unlock,
I see messages written in yellow in the upper corner of the screen like ("PAM:
brk increased by 40K" and "xscreensaver: child process X exited with SIGTERM"
(or something like that). These are probably debugging messages that need to go
Not a bug: you are seeing these messages because you turned on the "Verbose
Diagnostics" checkbox on the "Advanced" tab of the screensaver control panel.
Run "xscreensaver-demo" and un-check that box again.
I have never run xscreensaver-demo before in my life. I just ran it now and
confirmed that the "Verbose Dialognostics" [sic] box on the Advanced tab is
Well, I promise you, the verbose flag is on or you wouldn't be getting these
messages. Did you launch xscreensaver with -v? Is verbose set to true in your
~/.xscreensaver file or in the app-defaults file?
No -v. No .xscreensaver file. No verbose xscreensaver setting in my X
resources. I've changed nothing in my xscreensaver configuration or how I
invoke it, and yet these messages have started appearing when they were not
Perhaps the RPM is compiled in a way which causes these messages to appear when
they wouldn't normally.
Please do me a favor and stop treating me like an idiot (I don't know if that
was your intent, but it sure feels that way). Take a look at how many bugs I've
filed in bugzilla. I know a thing or two about reporting bugs.
Not to mention the fact that the first "xscreensaver" was written by me before
you even thought about writing yours :-).
I'm not treating you like an idiot. I'm telling you that I have no idea why you
are experiencing the things you are, and pointing out the only things that I can
think of that could be causing it. If you're taking that personally, I can't do
anything about that...
Has this ever reappeared? I can't reproduce it here.
I can't make it happen now, but I'm pretty certain I've seen the messages on my
xscreensaver window recently. I also see this in my .xsession-errors file,
which suggests that xscreensaver is sending it to stderr, and it shouldn't be:
xscreensaver: 23:04:06: PAM: brk grew by 40K.
xscreensaver: 23:04:09: PAM: brk grew by 8K.
I just checked my settings with xscreensaver-demo, and I don't have any verbose
settings of any sort enabled. I'm using xscreensaver-4.07-2. Here are my
xscreensaver does normally send that message to stderr. It implies a leak somewhere.
normally, meaning 'to stderr' as opposed 'to the screen'.
I can't reproduce this. Johnathan, if it happens to you again, can
you please reopen the bug?
To reproduce it, try locking the screen, and then entering a wrong
password to unlock the screen.
Just a "metoo" here. This *does* happen, just not reproducibly.
I came home to my system (FC2) today to see that exact message. Is
there a possibility that when drawing on a root window, that STDERR is
redirected to the screen somehow?
FWIW, I just experienced this exact problem with xscreensaver-4.18-4 on Fedora
Core 3. Screen is set to blank, verbose is disabled. However it did not result
from an invalid password attempt. I merely left my office for 2 minutes and it's
extremely unlikely that anyone tried to log onto my computer while I was out.
