Package: gcc-4.3
Version: 4.3.4-5


I recently started seeing several cases of gcc giving an error
message like this:
packet-l2tp.c:1680: error: unrecognizable insn:
(insn 419 86 84 9 packet-l2tp.c:1585 (set (reg:DI 200)
       (ne:SI (reg:DI 76 [ prephitmp.1208 ])
           (const_int 0 [0x0]))) -1 (nil))
packet-l2tp.c:1680: internal compiler error: in extract_insn, at

Note that there is a list of packages you could try to reproduce
it and a reduced test case in the debian bug tracker.

OK, I tested with gcc-4.4 since gcc-4.4.2-3 does not contain the patch for PR/42113, whereas gcc-4.4.2-4 does.

Verified that the two debian source packages, libssh2 and mpich2, when compiled with gcc-4.4.2-3 both generate ICEs of the nature shown above.

(The reduced test case in the debian bug tracker does not trip the ICE in gcc-4.4.)

Compilation with gcc-4.4.2-4 of these two packages is successful (well, I didn't let mpich2 go to completion but it got well past the point where the ICE was generated with gcc-4.4.2-3).

So looks like this bug is indeed PR/42113 and is fixed in current unstable gcc-4.4.

What is the timeframe for getting the Alpha buildds updated to a fixed version of gcc?
