<pre>This code, bug.cc, Clang just emits error message but misses line and column
number of it.
$cat bug.cc
void
foo () {
try { }
catch ( long () -> int ){}
}
$clang++ -c bug.cc
error: function with trailing return type must specify return type 'auto', not
'long'
1 error generated.
While in GCC
$g++ -c bug.cc
bug.cc: In function ‘void foo()’:
bug.cc:4:25: error: ‘type name’ function with trailing return type not declared
with ‘auto’ type specifier
4 | catch ( long () -> int ){}
| ^~~
Is it an valid try-block expression? I not sure about that. But anyway, Clang
should give appropriate full diagnostic message of it I think.
I have tested in recently released Clang versions, they all have this issue.</pre>
