So you can narrow it down to between revision 152380 and 152615.
My bracket is 152431 (no failures) and 152615 (failures).

Note that, as far as I have been told by Richard, the warning itself doesn't
point to an actual miscompilation in 4.4, because (PRE, etc.) aren't strong
enough. Thus, first people should double check that, and

Let's look at these tokens T()(int()) in detail.
(1) Yes T() looks like a function declarator:
T()(int())

(2) Then follows something in parenthesis, which looks a lot like C++03

I see. Seems a compiler problem indeed, because, as Jason mentioned, the
template is explicitly instantiated in string-inst.cc and marked to be exported
in the linker script for the *.so. I have no idea what

I tried 4.4.2 and do not any longer see the segfault on the Cray XT system. I
suspect this was fixed by addressing the problem noted in Comment #3.

Funny, and I agree the compiler should behave more gracefully, but this code is
invalid per 17.4.3.1.2: names containing a double underscore are reserved.

This is a linker bug. Recompiling without -g, so as to get error messages
without the unhelpful symbolic interpretation, I can reproduce

Looking at msmpeg4.s from PR 41567, build with -O2 -fPIC, we see
.LC2:
data8 mv_tables#+72
...
addl r14 = @gprel(.LC2), gp
We should not have spilled that address to the constant pool.
Add -mno-sdata and it gets worse -- LC2 moves from .sdata to
the .data.rel.ro section but

This code shows that the definitions for omp_integer_kind and omp_logical_kind
are missing from the omp_lib.h include file. If the module is used instead,
there is no error.
