fixed, any darwin-11-specific issues would perhaps be better dealt with in a
separate PR.

I can't reproduce the runtime failure with gcc-4.6-20110621 on x86_64-linux.

I see you're using Gentoo's modified gcc-4.4.5.  Can you please try again with
a g++ built from vanilla unmodified gcc-4.4.5 (or later 4.4.x) sources?

Of course I meant to write gcc-4.4-20110621 not 4.6...

Hi,
this is not really expected.  TLS was apparently binutils bug, while the
stringop-asm is linker plugin only problem (I sent 3 different fixes for that,
each of them wrong since we can't really immitate here the non-LTO behaviour
without tracking for every statement the originating LTO object file).

What problem you get on hppa?  Are you using plugin there?

I have this problem using the gcc 4.4.5 build in Ubuntu 10.10, which reports
itself as "gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5".  So it's not
Gentoo-specific.

That's also a heavily modified vendor compiler.

Please try with an unmodified 4.4.5 or 4.4.6.

Gentoo does not patch gcc severely.

See:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-devel/gcc/gcc-4.4.5.ebuild?revision=1.10&view=markup

which adds only 2 patches:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-devel/gcc/files/gcc-spec-env.patch?revision=1.6&view=markup
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-devel/gcc/files/4.4.0/gcc-4.4.0-softfloat.patch?revision=1.1&view=markup
(arm specific)

If that does not convince you, I can compile gcc without these patches. Just
say so.

Please note that runtime failure occurs in ~30-40% runs.

I don't think that .ebuild file describes everything in detail, specifically I
strongly suspect they also apply 27 patches from gcc-4.4.5-patches-1.2.tar.bz2.

I just recompiled the test case with a freshly built gcc-4.4.5 on x86_64-linux,
and ran it 100 times.  It failed zero times.

[Bug target/49530] New: Segmentation fault with -mint8

[Bug c++/49531] New: Doesn't resolve to conversion function template specialization in expressions

[schaub.johannes at googlemail dot com]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49531

   Summary: Doesn't resolve to conversion function template
specialization in expressions
   Product: gcc
   Version: 4.7.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: schaub.johan...@googlemail.com


GCC rejects this code, which I think is valid in both C++03 and C++0x

// snip
struct A {
  template operator T();
};

void f() { &A::operator int; }

main1.cpp:5:28: error: statement cannot resolve address of overloaded function

// snap

There is no overloaded function. The provisions of 13.4 apply when we are faced
with a function template name. We are not, in this case. 

"A specialization of a conversion function template is not found by name
lookup. Instead, any conversion function templates visible in the context of
the use are considered. For each such operator, if argument deduction succeeds
(14.8.2.3), the resulting specialization is used as if found by name lookup."

Before we even enter 13.4, we will do argument deduction and resolve to a
single function template specialization. After we resolved to that function *as
if by name lookup*, we will just skip 13.4 because we have a single function
name, rather than an overload set.
