------- Comment #2 from rguenth at gcc dot gnu dot org  2010-08-18 09:16 -------
With 4.5.1 I get (checking enabled)

VM.cpp: In member function 'gnash::VM::RNG& gnash::VM::randomNumberGenerator()
const':
VM.cpp:126:1: error: statement marked for throw in middle of block
# .MEM_19 = VDEF <.MEM_18>
D.294844_12 = OBJ_TYPE_REF(D.294843_10;D.294841_8->0) (D.294841_8);

VM.cpp:126:1: internal compiler error: verify_stmts failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

and with trunk I get

VM.cpp: In member function 'gnash::VM::RNG& gnash::VM::randomNumberGenerator()
const':
VM.cpp:126:1: internal compiler error: in create_linear_expr_from_tree, at
graphite-sese-to-poly.c:1207
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

4.4.4 works.
