I'm seeing what looks like a similar thing on trunk without having 
applied the patch:

FAIL: gfortran.dg/csqrt_2.f  -O0  execution test
FAIL: gfortran.dg/csqrt_2.f  -O1  execution test
FAIL: gfortran.dg/csqrt_2.f  -O2  execution test
FAIL: gfortran.dg/csqrt_2.f  -O3 -fomit-frame-pointer  execution test
FAIL: gfortran.dg/csqrt_2.f  -O3 -fomit-frame-pointer -funroll-loops 
execution test
FAIL: gfortran.dg/csqrt_2.f  -O3 -fomit-frame-pointer -funroll-all-loops 
-finline-functions  execution test
FAIL: gfortran.dg/csqrt_2.f  -O3 -g  execution test
FAIL: gfortran.dg/csqrt_2.f  -Os  execution test

(This is on Debian stable, with an unmodified trunk except for applying 
Richard Guenther's recent patch for fixincludes so it will bootstrap.)
