We have a STRING_CST in named_section.
The call to named_section comes from output_constant_def_contents.

------- Comment #6 from hubicka at ucw dot cz 2005-11-03 20:52 -------
Subject: Re: [4.1 Regression] WRITE(6,*) causes an ICE with -mcmodel=medium
OK, I think what is going on.
For some reason the code deciding whether data should be small or big
considers everything zero sized as unfinished potentially big. Not
quite sure why. This makes it to exceptionally consider zero sized
string constants small and to actually avoid named_section from
crashing...
I am not quite certain by both chunks, but it is best I can think of
today...
