[Fingerforce-devel] Bug#584563: enroll fails with error -22

[Christophe TROESTLER]

Hi,

I have the same error on a Thinpad W510.

# fprint_demo 
** Message: now monitoring fd 11

This is the only thing printed until one tries to register a finger.
Then nothing happens (and the green on the fingerprint readers does
not turn on).  Canceling the enrollment crashes the application with:

*** glibc detected *** fprint_demo: munmap_chunk(): invalid pointer: 0x000000000224c1a0 ***
