Traffic causing the crash:

... but basically any data over the wire (via telnet localhost 9000, for example) causes the same segfault.

I notice you're using Xdebug 2.1.0-dev, can you try with a stable release like 2.0.3 or 2.0.4?

Worse than that - was loading xdebug.so as a extension, not zend_extension. Will see if I can reproduce the crash in a more systematic way, but for now the basic connection setup and breakpoints work.
