Summary: executing a shell scripts gives a memory leak

Initial Comment:
Hi!

I've been trying to run a configure script, which gave me a 
huge memory leak. I've then created an empty script like 
this:

$ vi e
:wq
$ chmod +x e

then I wrote a script f that calls this empty script 100 times. 

for((i=0;i<100;i++))
do
./e
done

I've never written a shell script before, but it seems to work. :
-) Anyway, every time I call f, approximately 2700KB of 
virtual memory are gone. (I check this in the task manager.)

environment:
Windows 2000 SP4
gcc version 3.4.2 (mingw-special)
GNU ld version 2.15.91 20040904
MinGW-3.2.0-rc-3.exe
MSYS-1.0.11-2004.04.30-1.exe

The configure script I executed was from the k3d project. 
The task manager said, I was using 137740KB of memory. I 
ran 
./configure --without-docbook --without-gnome --without-gts 
--without-imagemagick --without-jpeg --without-openexr 
--without-plib --without-png --without-python --without-tiff

Memory consumption climbed up to 243396KB, then I got 
the error messages below. I also noted that the process IDs 
for the stuff called from the script climbed up to values 
>30000, which seems unusual to me. 

If you need to know anything else or want me to try sth, 
please drop me a mail. (Does sf.net do this automatically if 
someone adds a comment to this bug?)

Thanks
A. Haferburg

I believe I have a similar problem to this.  Its a critical 
blocking issue for me, because it means I cant actually run 
*any* configure script to completion, at least not using cccl 
(which obviously doubles the number of forks).

Can we bump up the priority a little please?
