[Bug c++/35319] New: [4.3/4.4 regression] ICE throwing fixed-point types

[reichelt at gcc dot gnu dot org]

The following valid code snippet triggers an ICE on mainline and 4.3 branch
when compiled with -O:

===============
void foo()
{
  throw 0r;
}
===============

bug.cc: In function 'void foo()':
bug.cc:3: internal compiler error: in write_type, at cp/mangle.c:1695
Please submit a full bug report, [etc.]

The code was invalid before GCC 4.3.0 and was simply rejected.

The code also ICEs without "-O".

This is most likely because there is no way to mangle fixed point types at all.
 So really I don't think this should be a P2 or marked as a regression until
the ABI has been finialized

Is there a mangling convention now for fixed-point types, or not?
If not, we should make this a sorry() and resolve this bug as SUSPENDED for
now.
If there is, well, you know, we should add it ;-)

Fixed-point constants are rejected by the C++ frontend since the patch for
PR39059.
