gcc is known to have various bugs when building on various platforms.
gcc is also known to have various bugs in optimisation levels over 1.
The gcc shipped with freebsd-4.2 had this problem, and I have a nasty
feeling that freebsd-4.3 is going to have a similar problem for people
who don't build it from the port.
In this particular case, gcc is generating an xor <register>, <register>
instruction which blanks the register. When you debug squid in gcc,
the pointer value becomes magically NULL, no matter what was passed
in to the function. This is obviously .. bad. :-)
