layout/generic/crashtests/438509-1.html hangs my debug build in table reflow.

STEPS TO REPRODUCE
0. build a Firefox debug build from mozilla-central
1. firefox -reftest layout/generic/crashtests/crashtest.list

ACTUAL RESULTS
100% CPU hang.  Looking at a reflow log it appears to be running
special-height table reflows repeatedly.
Let me know if you want me to generate a log file for you.

Removing all lines except 438509-1.html from crashtest.list
also reproduces the hang.

The hang occurs ~50% of the time.

PLATFORMS AND BUILDS TESTED
Bug occurs in Firefox debug trunk on x86-64 Linux.
No other platforms tested yet.
Bug also occurs in Firefox debug trunk on MacOSX 10.5.8 (x86),
although less frequently.
OS: Linux → All
Hardware: x86_64 → All
The crashtest pass on TryServer "Linux try hg unit test" hangs occasionally
due to this bug.
Same for me, using an opt build on Mac.  Loading 438509-1.html hangs Firefox about half the time.
