Re: [STUMP] Problem with Mathematica 6

[Kresimir Kumericki]

Dear Ian and Shawn,

thanks for your answers. Ian, thanks for Xnest-workaround script.
I had some funny experiences with Xnest in the past (similar to what you 
mention),
so I am not sure this will be good enough for me (I really use Mathematica a 
lot).

Shawn, thanks for trying to help. I'll try to answer your questions:

I am attaching the strace of crashed SBCL stumpwm and, yes, it's 
using 100% of the cpu.

I have now. (Debian etch has too old clisp, so I compiled new clisp-2.45
and included new-clx module. However, I couldn't include libsigsegv for
some reason. I hope this is not essential.)

It turns out that clisp version of stumpwm behaves differently when
strace is on. Without strace, after starting Mathematica, it always crashes 
completely (process 'stumpwm' is killed) and I am returned to xdm login
screen.

If I start it with 'strace stumpwm > logfile' in .xsession, then it
never crashes completely but
starting Mathematica forces it to restart with unhandled error which I
also attach. (After this error is reported, restarted stumpwm normally works,
but there is no frame for Mathematica window which is now inaccessible,
although it is running.)

In ratpoison I get for troublesome Mathematica 6 window

WM_CLASS(STRING) = "XMathematica"

while nice-behaving Mathematica 5.2 window is:

WM_CLASS(STRING) = "Untitled-1", "XMathematica"


I don't know if any of this helps.
