I have encountered a strange issue with Pasgui's 64-bit build hanging on 64-bit Ubuntu 12.04 LTS.
I have an SVN sandbox in a sub-directory on /opt with Access Files permissions set for the Others group. Regular users can open all the files without problem in a normal text editor. Logged in as a regular user, I can add a file from /opt to a CodeBlocks project but as soon as I try to open the source file in CodeBlocks, CodeBlocks hangs consuming 96-100% of the CPU. (A real hang - I left it for an hour and it was still hung!)
If I login and repeat as the 'admin' user (but not running anything as superuser), I have no problems.
When I checkout the same sandbox into a sub-directory in /home and add a file from there, no hangs.
Even more bizarrely, I have repeated all the above on 32-bit Ubuntu with an identical setup and although there is a noticeable pause when I open an /opt file in CodeBlocks as a regular user, I see no hang.
Anybody any ideas? The fact that CodeBlocks hangs rather than omitting an error message is worrying.
