I am facing a very strange problem. Texmaker quits with an error under a very specific condition, which has nothing to do with compilation, but rather what I type. Say for a minimal working example, I start typing


If I now try to type domain I get to do, pressing m or any other character exits Texmaker with the following:

*** glibc detected *** texmaker: free(): invalid next size (fast): 0x0000000002d67de0 ***

There are a lot more lines to it. Including these libraries: libc.so.6, ibQtGui.so.4, libQtCore.so.4, libglib-2.0.so.0

I don't recall having had this problem before and it seems to be a problem with the interface (Qt) I guess. I believe this will also work with other latex environments, not just tikzpicture, but haven't found any yet.

Using \begin{tikzpicture} makes the following lines appear orange. Typing do appears in blue as would for. It seems Texmaker recognizes that a code is to follow, or something of the sort. But it does not crash when typing for.

I am honestly lost as to how to fix this. Any ideas?

I am using: Linux Mint 13 Maya MATE, Texmaker 3.2, Texlive 2012

Also: This only happens if do are the first characters on a new line.

Full error output here

UPDATE: The problem seems to be version specific. I installed Texmaker 3.3 and do not face this problem any more. I have also installed Texmaker 3.2 on another Linux machine and face the same error.

Interesting indeed. What happens if you paste the whole word directly? – percusse Sep 6 '12 at 21:47
copy/paste of the entire word works. – Markus Sep 6 '12 at 21:50
I don't know much about TeXmaker but is there any macro/plugin that tracks your input for auto-replace or something along those lines? – percusse Sep 6 '12 at 21:52
