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

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

4.4.4 works.

(fairly stupid) Workaround

Attaching workaround for people coming across this bug report when googling the
error message.

Thanks HJ for reducing this.
I looked at this change and it looks simple enough to backport it to 4.5.

Can't reproduce with current trunk,
./cc1plus -m32 -O2 pr45314.ii -quiet -floop-interchange
is fine.
