Given that in another email he mentioned that running eclipse as root
doesn't crash, then it's more likely that the problem is due to the
updating of various eclipse files in the user workspace.

To confirm, just try starting eclipse with a different workspace, using
the following (untested)
$ eclipse -data /home/fb/eclipse_test_workspace

Also compare
/home/fb/eclipseWTP3.2.3/configuration/org.eclipse.osgi/bundles/151/1/.cp/libswt-pi-gtk-3657.so
against 
/usr/lib64/eclipse/configuration/org.eclipse.osgi/bundles/151/1/.cp/libswt-pi-gtk-3657.so
and see if the corresponding one on the system both exists and is the
same. (particularly since this appears to be your problem file)

I suspect not. I thought that updating of various core 
libraries/bundles of eclipse was disabled on most linux distros due to
eclipse being built against the system version of glibc, but a update
there is the only way I can think that it could go from working to
crashing after an eclipse update.
