But there is a latent bug. I don't know a way to reproduce this without Feng's
patch in C or C++, maybe Ada. But the bug is still there.
Here is the reduced testcase that passes at -O0 but fails at -O1.
CHARACTER*10 INTSTR
CHARACTER C1
DATA INTSTR / '0123456789' /
C1 = INTSTR(1:1)
print *, C1
if(C1 .ne. '0') call abort()
end
