1+1 in wxmaima => maxima crash

[Johan Christiansen]

Binary package hint: maxima

wxMaxima 0.6.4 http://wxmaxima.sourceforge.net
Maxima restarted.
(%i1) 1+1;
CLIENT: Lost socket connection ...
Restart maxima with 'Maxima->Restart maxima'.

Restarting maxima does not help. It fails everything!

Downgrading the maxima package makes it work... But that's a breezy package.

Since maxima is crashing, why is this a wxmaxima problem? Can you please provide a backtrace following http://wiki.ubuntu.com/DebuggingProgramCrash ? Thanks.

Maxima only crashes when run from wxmaxima. Running in terminal, maxima is working fine. So i can't figure out wether it's a maxima or a wxmaxima problem.

Without installing debugging symbols, here is what i get:

johan@home:~$ ps aux|grep maxima

It seems that maxima isn't crashing afterall. Somehow it's told to exit normally...

Here's a screendump of what is happening.

I have the gdb debugger attached to the underlaying maxima process while typing 1+1; in wxmaima.
BTW: My friend also has this problem on his i386 with a clean install of dapper.

Rejecting as duplicate.
