>Environment:
(i'm not actually running this software version; i know the bug existed some time ago, and i just downloaded the latest snapshot (20050402) to verify that it does indeed still exist)
>Description:
My earlier post fully outlines the issue:
http://lists.freebsd.org/pipermail/freebsd-emulation/2003-August/000136.html
>How-To-Repeat:
In some configurations, it's a problem; in some it isn't.  Ironically, the configurations for which it isn't a problem are the buggy ones; the configurations for which it _is_ a problem handle the statically defined variable properly.  This is likely due to the use of different versions of gcc, though other factors may be involved.  I didn't research this thoroughly, since correcting the issue was simple enough.
