Description Juan Ramón Molina Menor 2015-09-22 21:26:16 UTC 
FreeBSD-CURRENT r288108, libfprint-0.6.0 and pam_fprint-20080330_1. Not using fprint_demo.

One time in two, pam_fprint_enroll, login or su fail with the following error:

(process:1232): GLib-ERROR **: gmem.c:134: failed to allocate 18446744073709551612 bytes
Trace/BPT trap

The following execution of pam_fprint_enroll, login or su work (as long as the fingerprint is recognized, which is not always easy!). This "fails every two times" is strictly repeatable.

The fingerprint reader is recognized as a Validity VFS5011 on my Lenovo ThinkPad S440.

I have only found another reference to this error:

Over to glib maintainers
Comment 2 Walter Schwarzenfeld freebsd_triage 2018-01-13 01:10:48 UTC 
Is this still relevant, or could it be closed?
Comment 3 Juan Ramón Molina Menor 2018-01-13 14:00:52 UTC 
I have not tested it in a while. I’ll do it as soon as possible an report back.
Comment 4 Juan Ramón Molina Menor 2018-01-13 17:32:40 UTC 
The error persists with a quite current system:

FreeBSD 12.0-CURRENT r326497 (Dec 3 2017).

I upgraded the fprint ports, but they are still at the same major version:
libfprint-0.6.0_3
pam_fprint-20080330_1

And GLib: glib-2.50.2_7,1

Still a problem with libfprint-0.7.0 and glib-2.56.1_1,1 ?

Yes, the problem persists once every two tries. I have just updated the system to 12-ALPHA8 and upgraded the packages.
