Description David Binderman 2005-08-30 20:41:49 UTC

Description of problem:
I just tried to compile package xorg-x11-6.8.2-45 from Redhat
Fedora Core development tree with a special development version of the
GNU C compiler.

The compiler said

1.

DigitalEdge.c:616: warning: array subscript out of range

The source code is

	pressure = priv->dedgeData[6] + (priv->dedgeData[5] >> 4) * 128;

but earlier in the same file,

    unsigned char dedgeData[5]; /* data read on the device */

so priv->dedgeData[6] and priv->dedgeData[5] doesn't exist. 

Suggest code rework.

http://bugs.freedesktop.org in the "xorg" component is the proper place
to report compiler warnings and other developmental bugs to X.Org developers.
