Hi Amos,

It seems that there is an assert() that is setting something, instead
of just checking something.
I can reproduce the problem *without* redefining debugs(), just by
compiling with NODEBUG.
So now I can provide you a cache.log in case you think it would help.

And on the other hand, I get a fully functional Squid by using a
different macro name, like you suggested.

Alan
