          Severity: minor
          Priority: P3

source code which fails to compile

Hi,

I've found a possible bug in gcc. I've attached a source code which fails to
compile with:

'g++ -c -O2 inline_problem.cpp'

Gcc prints:
inline_problem.cpp: In function ‘void bar(Foo&)’:
inline_problem.cpp:24:60: error: inlining failed in call to always_inline
‘Delegate<void(PAR)> delegate(OBJECT&, void (OBJECT::*)(PAR)) [with OBJECT =
Foo; PAR = int]’: mismatched arguments
inline_problem.cpp:35:27: error: called from here

The code compiles, if you do any of the following:
* remove '-O2'
* replace 'sint' with 'int' at line 32
* remove one of the 'delegate' calls from the function 'bar'

It fails to compile with 4.4.6, 4.6.3, 4.7.2.
However, it compiles with 4.5.3.

g++-4.7 -v prints:
Using built-in specs.

I can confirm that mainline is fine. Shall we close this?

Sounds like dup of PR52888.  Richard, is that safely backportable, or not?

Yes, looks safe to backport, and indeed a dup.
