I add a debug patch to output the length of data.

Could you try it?
the 32bit rpm doesn't "perfectly" fit into my 64bit system, but there is
--nodeps et voila ;-)
with your 32 bit iwevent image I get two more lines of output before it
crashes: while the 64bit prog crashes after 'Set ESSID:"context"' your 32bit
bianry prints 'Association Response IEs:...' and 'New Access Point/Cell
address' :

strlen data is 1, len is 15.
