Unfortunately, I don't. A brief google search also did not provide much 
clues. It was on some GCC related list (or GCC's bugzilla).

IIRC, an RTEMS user had reported RTEMS paranoia was not providing the 
expected results. When reporting this issue, some GCC devs stepped in 
and begun tearing paranoia apart.

  Answers were along the lines of "bad, outdated code", "non-portable", 
"invalid testcase". The outcome had been "works sufficiently well for 
RTEMS in many cases".

Also, I could bet, Joel had been involved.
