<pre>Is the libstdc++ that the Xserver sees replaced? If the server is picking up
the wrong libstdc++... yeah, don't do that. You wouldn't replace parts of your
car engine with random parts from a different model, would you? :)
If the driver loaded by the server is still using the correct system libstdc++,
it should work fine. Two things to try:
1. Try running the app with LIBGL_ALWAYS_INDIRECT=y. Does it still crash the
server?
2. Try collecting an apitrace of the application. You'll probably have to run
it via ssh or from the console. Otherwise everything will be forcibly killed
when the server dies, and you won't get a trace. It might be sketchy any way.
Does replaying the trace on an unmangled system still crash the server?</pre>
