The contents of the buffer *foo* are below.

I'm not sure if you caught one of my previous messages, however, so I'd 
like to repeat:

The problem is easily repeatable in the above scenario. But not if I 
change "InconsolataLGC" to "Inconsolata LGC". Then the resizing stops 
after the first iteration.

In either case, 'M-x describe-face RET default' shows "Family: 
Inconsolata LGC", though. So it's not like "InconsolataLGC" is entirely 
unrecognized.

Anyway, here's the log (evaled the form 3 times):
