I know of the -d option to switch some "debug mode"...
Is it, what you mean ?
For builing blender I use the following script:
sudo make install
sudo rm -rf newdir
If the "debuggin blender is the default, then...
Please inform me, if not...I will rebuild blender then...

I built the Linux-Kernel with agpart support for Radeon 7500/ATI
as module, installed the kernel and reboot.
I checked the logfile of XFree and found hw drm/dri enabled.
I start blender and after some renderings it crashes as before.
I rebuilt XFree (4.2.0/4.2.1/18.104.22.168/4.99.3), installed it and
found that the kernel module "radeon.o" was found too old by
XFree, so I cd to
compiled the radeon.o there and cp'ed it to
After reboot I either had no hw dri/drm support (blender runs
more stabel) or I got hw dri/drm support up and running
(sometimes way slower than emulated via software...the world is
a patchwork of wonders...) and blender crashes by pressing
RENDER/ANIM and/or by aborting a rendering by ESC or because
just wants to crash.
Currently I am running XFree 4.2.1 again with hw dri/drm.
Because I again kill my machine (just kidding) ket me write down
this mail before experimenting with blender again...

You are the doc, Doc!

May be it is simply too advanced and my XFree is to simple ? ;)
