Keyboard input in Javascript file causes seg fault

[Ben Linsey-Bloom]

Running Bluefish 2.2.2 on Ubuntu 12.04 64-bit.

To recreate the Bluefish crash:
1. Create new file

2 . Paste in this line:
tagCloud.innerHTML += '&nbsp\; <a href="javascript:tagClick();" style="font-size: ' + tags[i].size + '%\;">' + tags[i].id + '</a> &nbsp\;';

3. Save as a Javascript file (choose any file name with '.js' extension). Bluefish applies Javascript colours to the code.

4. In the code, locate 'tagClick()' and quickly try to put two single quotes (the ' symbol ) in the parenthesis '()' so 'tagClick()' becomes 'tagClick('')'.

If you type slowly it might be okay, but if you type the single quotes quickly, bluefish crashes on my machine every time.

Run from the terminal I get this result:

ben@mr-shinyface:~$ bluefish
Language statistics for Javascript from /usr/share/bluefish/bflang//javascript.bflang2

I'll keep trying to narrow it down and see exactly which part of this code is causing the problem. Please get back to me if you need more info.

I've found that disabling Document > Highlight Syntax stops the bug from occuring.

Please install bluefish-dbg and gdb. Then run `gdb' and inside the debugger session type `set logging on' and `r bluefish'. Reproduce the segmentation fault. When the program stops and gdb reports the error, then type `bt full', then quit and attach the gdb.txt file to this report. See also

I created a backtrace and opened a report in the upstream bug-tracker. You don't need to do it.

Awesome thanks for the speedy response.
