I am seeing something similar when compiling glibc
with trunk 20141001 with only -O2.

../iconv/skeleton.c: In function ‘gconv’:
../iconv/skeleton.c:792:1: internal compiler error: in check_probability, at
basic-block.h:959
 }
 ^
0x10685aa check_probability
    ../../src/trunk/gcc/basic-block.h:959
0x10685aa apply_probability
    ../../src/trunk/gcc/basic-block.h:988
0x10685aa compute_outgoing_frequencies

0x10685aa find_many_sub_basic_blocks(simple_bitmap_def*)

Code ok with 20140927.
