What binutils version are you using?  do ld --version.  This might be a bug in

Jakub,

the error message I get below is new with gcc 4.5, and is still present as of
revision 148276 (20090608). Is there any info I can provide (e.g. attach the
object file?) that could help in getting this resolved as either a gcc or a
binutils issue.

Joost

Couldn't reproduce (just built cp2k on x86_64-linux with trunk gfortran and
.eh_frame_hdr has been created just fine).  I'm using binutils 2.19.51.0.2.

Anyway, you should probably just tar up the .a library and other things you are
linking together and with that report it in binutils bugzilla.

It seems to depend on the compilation options as well. The sopt compile (in my
case :
FCFLAGS  = -O2 -ffast-math -funroll-loops -ftree-vectorize -march=native
-ffree-form $(DFLAGS) -I$(GFORTRAN_INC)
goes fine, while a -O0 compile (sdbg compile with flags:
-O0 -g -ffree-form $(DFLAGS) -I$(GFORTRAN_INC) -fbounds-check
)
produces warnings. In fact, the number of errors depends on the precise
options. With -fbounds-check present, there are more errors than without the
flag. Any 
chance you could try that ?
make distclean

We ran into this bug recently, running tests against a GCC (4.5 precursor)
snapshot.  Discussion here:

[mmitchel at gcc dot gnu dot org]

------- Comment #13 from mmitchel at gcc dot gnu dot org  2010-02-17 17:15 -------
I reluctantly agree with Ian's comment in:

http://gcc.gnu.org/ml/gcc/2010-01/msg00332.html

that:

"I think it would be troubling if a gcc release required a very new
binutils release on a popular platform like x86_64."

I actually think we should be unsympathetic to this kind of mixing of
components.  GCC is the only major compiler that does not consider the
compiler, assembler, and linker to be a "single unit".  We've made the problem
harder for ourselves than it needs to be, for the dubious benefit that users
can download a new GCC release without having to get a new assembler and
linker.

However, even though I think our policy is counterproductive, it is in fact our
policy.  We shouldn't change the policy by accident; we should change it
through conscious decision.  Until then, we should indeed to as Ian suggests
and:

"modify
the configure test for gcc_cv_as_cfi_directive to avoid the problem
when using an older binutils"
