The following semi-invalid code ICEs (but compiles fine with ifort):
MODULE f03_test
USE, INTRINSIC :: ISO_C_BINDING
INTERFACE
FUNCTION build(lib, np) BIND(C)
END FUNCTION
END INTERFACE
PROCEDURE(build), POINTER :: pbuild
CONTAINS
SUBROUTINE test_asc()
END SUBROUTINE test_asc
SUBROUTINE test_bind_c BIND(C,name="test_bind_c")
END SUBROUTINE test_bind_c
END MODULE f03_test
END

Before the ICE one gets the error:
SUBROUTINE test_bind_c BIND(C,name="test_bind_c")
1
Error: Missing required parentheses before BIND(C) at (1)
If this error is corrected, the ICE goes away.

that's why I called the testcase semi-invalid. Note that g95/ifort/NAG appear
to allow this (non-standard) variant.

Not related to ISO-C.
Reduced test case:

INTERFACE
INTEGER FUNCTION build(lib, np)
END FUNCTION
END INTERFACE
PROCEDURE(build), POINTER :: pbuild
CONTAINS
XXXX ! simply generate any error
END MODULE f03_test

------- Comment #7 from dominiq at lps dot ens dot fr 2010-07-26 13:30 -------
This pr looks like a duplicate of pr37744, or at least the ICEs disappear with
-fwhole-file (now the default: see
http://gcc.gnu.org/ml/gcc-bugs/2010-07/msg02853.html#c9 ).

Both comment #0 and comment #6 work for me without ICE on 4.6 trunk r163095.
Closing as fixed.
