 Hi,

 It seems that "some" file-targeted printf end up in coredump.
 (I say "some" because first few succeeds without clear reason. Ie: first 
 few logs work (and end up in the file) then one makes dumping guts also 
 without good reason)

 Removing logs from source allows the emulator to run until it hits 
 another log.

 System is 11-CURRENT, r256440, amd64
