The crash looks like a core Xserver bug, but it could be one of the DDXs
feeding in garbage. Double checking with an older Xserver seems reasonable.

X is a setuid root binary - it has to be very careful what environment
variables it uses (basically it can't trust any of them). The path X uses to
load its DRI interface is determined at compile time by `$PKG_CONFIG
--variable=dridriverdir dri`
