Hello Everyone and a special hello to Dr. Vaughan :-) ,

I am attempting to run playerstage on a custom configuration and world file
which results in a segmentation fault. There was only one post with similar
problems that I am having (
http://old.nabble.com/Segmentation-fault-on-loading-model-to31598877.html#a31598877
Segmentation-fault-on-loading-model ) but it does not have a solution (yet).
I am currently running player v3.0.2 and stage plugin v3.2.2 on Ubuntu 10.04
64-bit. I obtained both the packages from Toby Collet's launchpad site.
However, the worlds file directory was not installed directly to
/usr/share/stage/worlds/ (I don't know why) so I had to copy the worlds file
directly from stage-3.-2.2 source directory.  I have added all the files
that I think is necessary to determine the problem I am having, please let
me know if you need additional information.

When I run player with the attached cfg1.cfg file, I get the following
output:

I ran player using gdb to determine the cause of the segfault:

 [Loading ./cfg1.world][Include /usr/share/stage/worlds/pioneer.inc][Include

loc=0x7ffff0626580) at strtod_l.c:530
530	strtod_l.c: No such file or directory.
	in strtod_l.c

The world files were originally written for stage2, but using the wonderful
guide provided by Jennifer Owen (
http://www-users.cs.york.ac.uk/jowen/player/playerstage-manual-update.html
playerstage-manual-update ) I was able to update the required files,
although I might have messed up something that could've caused the
segmentation fault.

I looked for strtod_l.c on my system and without surprise couldn't find it.
At this point I am not sure how to proceed. Any help is very much
appreciated. 

Thanks!
