I don't think this is a bug...

You cannot compare PChar strings directly using the "=" operator; use
functions such as strcomp instead. PChar is just a pointer type, and "="
will compare the address.
"p='T'" is a special case: Here the compiler does an automatic pointer
dereference, and as PChar is equivalent to ^Char, it's clear that this
comparison will check the first character of p.
