Shawn & Gergely--

I spent a few hours tonight trying to track down the memory
issue.  When I attached gdb to the ratpoison process (there
were three, actually), I did a backtrace and discovered the
following, repeated many hundreds of times:

#0  chunk_alloc (ar_ptr=0x4015c1a0, nb=24) at malloc.c:2801
#1  0x40101b95 in __libc_malloc (bytes=13) at malloc.c:2561
#2  0x804e62c in setenv (name=0xbbe80a84 "DISPLAY", value=0x917cff0
":0.0",
    overwrite=1) at actions.c:2091
#3  0x400debce in putenv (string=0x917cfe8 "DISPLAY=:0.0")
    at ../sysdeps/generic/putenv.c:63
#4  0x804e67a in setenv (name=0xbbe80ae0 "DISPLAY", value=0x917cfd8
":0.0",
    overwrite=1) at actions.c:2096
#5  0x400debce in putenv (string=0x917cfd0 "DISPLAY=:0.0")
    at ../sysdeps/generic/putenv.c:63
#6  0x804e67a in setenv (name=0xbbe80b3c "DISPLAY", value=0x917cfc0
":0.0",
    overwrite=1) at actions.c:2096
#7  0x400debce in putenv (string=0x917cfb8 "DISPLAY=:0.0")
    at ../sysdeps/generic/putenv.c:63

(rest snipped)

So that led me to the actions.c file.  I was wondering why
setenv was getting called, since I know my libc has it
compiled in.  The 1.1.1 version of actions.c has this macro
defined:

2081: #if !defined(HAVE_SETENV) || !defined(setenv)

The 1.1.0 version has this:

2075: #ifndef HAVE_SETENV

Obviously, something on my system is botched up.  At any
rate, I replaced the former with the latter, problem solved.

Any idea why this method was called over and over?  It
almost looks like a runaway recursion...

Any other info I can send your way to figure out a fix, let
me know.  I'm in good shape now, xsetroot works and I still
have some memory left over :)  I'm wondering if anyone
else is running into this problem (it really brings the
machine down hard if you're not quick and kill it
before it gets out of hand).

Thanks for the help!
