I tried to reproduce this, but the given example works fine on my 7.3.*
installation. I also looked through the post-7.3.1 changes in the 7.3
CVS branch to see if there was anything related, but didn't see
anything.
One possible theory is that you didn't do a clean rebuild after updating
your source tree to 7.3.4 ... but I'm not sure how tenable that is; it'd
only be likely to matter if we changed in-memory data structures in the
7.3 branch, and I didn't notice anything like that in perusing the logs.

Could you provide an *exact* sequence-to-reproduce rather than
handwaving? Maybe I'm just missing the problem. Also, what platform,
