>Description:
[ Reported to the Debian BTS as report #186299.
  Please CC 186299@bugs.debian.org on replies.
  Log of report can be found at http://bugs.debian.org/186299 ]
	

Rechecked with 3.2 20030314 and 3.3 20030404.

While building php3 on unstable/powerpc, gcc-3.2 ICEs on a file that gcc-2.95
handles fine.  Attemps were made with gcc-2.95 (success), gcc-3.2 (fail), and
gcc-snapshot (fail).

Using -O0 or omitting -fPIC doesn't show the ICE.

$ gcc -c -fPIC -O1 pack.i
../functions/pack.c: In function `php3_unpack':
../functions/pack.c:807: error: unrecognizable insn:
(insn 1275 1022 3 0 (nil) (set (reg/v:DF 311)
        (const_double:DF 0.0 [0x0.0p+0])) -1 (nil)
    (nil))
../functions/pack.c:807: internal compiler error: in extract_insn, at recog.c:2175
