------- Comment #1 from dominiq at lps dot ens dot fr  2010-03-30 20:00 -------
Confirmed:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000
0x00000001000674c8 in parse_spec (st=ST_INTERFACE) at

Not a regression, I get the "Bus error" for 4.2.4, 4.3.4, 4.4.2, and trunk.
