I recently updated my machine from CentOS version 6.5 to 6.6. Subsequent to the update, ccstudio 5.5 would crash every time I ran it. Here's an example:
galens@lion:~$ ccstudio ccstudio: cairo-misc.c:380: _cairo_operator_bounded_by_source: Assertion `NOT_REACHED' failed. Aborted (core dumped)
This appears to be related to the following eclipse bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=441705
Here's a workaround that is being used by other eclipse users. Append the following line to your ccstudio.ini file.
-Dorg.eclipse.swt.internal.gtk.cairoGraphics=false
Presumably this would apply to RHEL and Scientific Linux 6.6 users as well. I don't know whether other versions of ccstudio are affected.
