That was indeed the right place for the change. No, nothing else gets 
broken, that macro was only used there.
Now I have committed the fix that allocated memory dynamically for the 
headers, so if you upgrade you will never see this problem.
> The header I'm having a problem with is "P-Asserted-Identity", 19 characters long.  Shorter ones have no problem.  Perhaps there is a maximum length defined somewhere?  If so, I couldn't find it.  I tried changing HDR_DEFAULT_LEN in b2b_logic/b2b_logic.h from 7 to 14.  This caused problems.

The HDR_DEFAULT_LEN is used for something else - the b2b_logic module 
had a list of default headers that must be passed from one side to the 
other, and this macro says how many they are.
