struct H {
operator char();
operator short();
};
int const& ref = H();
output:
oref.cpp:7: error: conversion from 'H' to 'const int' is ambiguous
oref.cpp:4: note: candidates are: H::operator short int()
oref.cpp:3: note: H::operator char()
oref.cpp:7: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in initialize_reference, at cp/call.c:6586
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL: http://gcc.gnu.org/bugs.html > for instructions.
using:
$ g++ -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc/configure --enable-languages=c++,c --enable-
threads=posix
Thread model: posix
gcc version 4.0.0 20050203 (experimental)
This is a regression from earlier versions. There does not seem to be any
problems if I do the reference binding in block scope.

Confirmed, I think is a regression (even though it does not show up with checking).

It is also a 3.4 regression too:
: Search converges between 2003-06-19-trunk (#269) and 2003-06-20-trunk (#270).
