[Bug middle-end/33216] New: [4.1/4.2/4.3 Regression] ICE in named_section_real, at varasm.c:419

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

static void (*const __CTOR_LIST__[1]) (void) __attribute__
((section(".ctors")))
  = { (void (*) (void)) -1 };

void __libc_global_ctors (void)
{
   run_hooks (__CTOR_LIST__);
}


ICEs with 4.1 with -fprofile-arcs:

gcc -S bug-292513.3.min.i -fprofile-arcs
bug-292513.3.min.i: In function '_GLOBAL__I_0___libc_global_ctors':
bug-292513.3.min.i:7: internal compiler error: in named_section_real, at
varasm.c:419
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugs.opensuse.org> for instructions.

and is rejected with 4.2 and trunk with -fprofile-arcs
bug-292513.3.min.i: In function '_GLOBAL__I_0___libc_global_ctors':
bug-292513.3.min.i:1: error: __CTOR_LIST__ causes a section type conflict
bug-292513.3.min.i: At top level:
bug-292513.3.min.i:1: error: __CTOR_LIST__ causes a section type conflict

this is both a regression to 4.0 which happily accepts the code with
-fprofile-arcs.

Possibly related to PR31490.
