[Bug 301192] [NEW] libxcomp crashes on linux-sparc

[Frank Schaefer]

Public bug reported:

On Linux-SPARC builds of nxcomp, libxcomp consistently gets whacked by
SIGBUS due to unaligned memory accesses.  This causes nxproxy to crash
whenever anyone tries to connect, and all nxclient sees is a sudden
connection reset.

libxcomp actually has codepaths to handle access alignment when
required, but they're triggered on "#ifdef __sun" rather than "#ifdef
__sparc".  The attached patch adds checks for "#ifdef __sparc" where
appropriate.  With this patch, freenx-server as a whole now appears to
be stable on SPARC (at least built from the source packages for Ubuntu
8.04).

This is an upstream bug, so I plan to report this to freenx.berlios.de
as well.

** Affects: nxcomp (Ubuntu)
