wxmaxima crashes when typing parentheses () or [] in the Plot 2D Dialog-Window

Bug #1311770 reported by Christian Prim on 2014-04-23
This bug affects 6 people
Affects Status Importance Assigned to Milestone
wxmaxima (Ubuntu)

Bug Description

What must be done to reproduce:

Start wxmaxima. In Plot-Menu select 'Plot 2D'. Type in the first line where the %-sign is an opening bracket (.

What happens:

wxmaxima crashes

What is expected:

the plot of a given function eg. sin(x).

In preferences matching parentheses/brackets is selected. If not, () works in 2D-Dialog box.


[] never works in main window. The preferences don't change the behaviour.

maxima itself works without problems (tested in terminal).

I notice that it occurs when I use the handy windows that pop up when you use the menus to help the novice get what they want. If you type the command in the regular work window, parenthesis work fine. I'm using wxMaxima 13.04.2 on Ubuntu 15.04 with wxWidgets 3.0.2-1. The plot2D function is not necessary. It seems any of the windows from the menu if you type the first (, it crashes. When I run gdb and type the (, I get the following:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff499fc3e in ?? () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0

So I installed libglib2.0-0-dbg and did it again. I get:

I ran wxmaxima at the terminal and got the following backtrace that might be helpful.

I find the message as to where the segfault occurred changes when I swap to different menus. For example when I choose the solve instead of integrate as I was using, I get:

I guess this means I don't know what I'm doing, and there are probably a number of threads, and I don't know how to get the one that is segfaulting or something.

I don't think this a a duplicate of https://bugs.launchpad.net/bugs/1308154 as is claimed here. I can enter brackets just fine at the regular command line and I get a nice pretty printed a_0 for a[0].
