[Vala] Vala app crashing in vprintf on 32-bit arches, not on 64-bit arches

[Michael Gratton <mike vee net>]

Hey all,

Geary is suffering a bug which is causing it to frequently crash on 
32-bit installations, in a place where it doesn't crash on a 64-bit 
install. The crash occurs in vprintf, during a call to GLib.debug() 
from an async method. Looking at the log line on a 64-bit machine, the 
args passed to it seem valid, and after both having a look at the 
generated C files on both arches they seem like they should be working 
fine and appear to be identical.

Does this ring a bell for anyone? Should I be looking at libc or glib 
instead?

Details are in <https://bugzilla.gnome.org/show_bug.cgi?id=745165>, 
best stack trace we have at the moment is here: 
<https://bug758621.bugzilla-attachments.gnome.org/attachment.cgi?id=329846>

Thanks,
//Mike
