htop quits unexpectedly after SortBy (with workaround)

[kfigiela]

Just after pressing F6 (SortBy) command htop quits printing following to the console: "htop 0.8.2.1 aborted. Please report bug at http://htop.sf.net". This happens with self-built htop from Git source as well as with the one that comes from MacPorts.

There's a workaround, after starting htop open "Kill" menu, and then cancel. After this, sort works fine.

The fuFunctions array for the Sort Screen's FunctionBar is not ended with a NULL Pointer, thus strdup reads from invalid address when creating this FunctionBar. The following patch (unified diff) adds a NULL Pointer to the two fuFunctions arrays in htop.c not ending in an NULL pointer:

AndyA can you add this patch to your repo?

[andyzweb]

how can I apply that patch to my copy?

[xyb3rt]

Something like: `patch -u < FILE'. See the patch man-page for more details.

[xavierlacot]

I can confirm that applying this patch worked for me. Thanks!

[stepchud]

See my recent comment/pull request for the applied patch. Hopefully AndyA will accept it since I like htop on osx and this was the one bug that was buggin' me. :)
