I can reliably trigger this XFS_WANT_CORRUPTED_GOTO() with a
fsstress that fills the filesystem:
xfstests> ltp/fsstress -d /mnt/scratch -s 1370236858 -p 512 -n 8192&
Hasn't reproduced after 10 minutes of running at ENOSPC here - how
long does it take to reproduce? What storage hardware are you
testing on? How many CPUs? RAM? ....

A 7-8 hours on spinning rust. This is my burn in test.
