[Bug c/37858] New: [4.3/4.4] ICE when "-fdump-ipa-all -dv" is used

[zsojka at seznam dot cz]

gcc crashes when any file is compiled with following switches:

gcc test.cpp -o test.o -fdump-ipa-all -dv

-----------

Seems to crash for any valid input file, but in this test I used:
test.cpp:
int main(void) { return 0; }

-------------

test.cpp:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.gentoo.org/> for instructions.

Confirmed, gcc crashes in passes.c, around line 1288:

  if (initializing_dump
      && dump_file
      && graph_dump_format != no_graph
==>   && (cfun->curr_properties & (PROP_cfg | PROP_rtl))
          == (PROP_cfg | PROP_rtl))
    {
      get_dump_file_info (pass->static_pass_number)->flags |= TDF_GRAPH;
      dump_flags |= TDF_GRAPH;
      clean_graph_dump_file (dump_file_name);
    }

(gdb) print cfun
$1 = (struct function *) 0x0
