Which version of wpa_supplicant is this based on? Is the customized
driver interface source code available somewhere?

This is not from the basic wpa_supplicant package, so I cannot help with
it without seeing the source code for the code that generated this

I would expect this to be fixed in the current development branch. If
not, I would certainly like to here more details; e.g., a backtrace from
the coredump file or the same test run under valgrindg.

Could you please try this under wpa_supplicant 0.5.5? It won't fix any
problems that may be in the driver interface code, but it may remove
this segfault.
