Most likely this has to do with something before the declaration
in question, not being properly terminated or something like that.
It could be many lines earlier.

Sorry, I don't know how hydra works.  But if you control its inputs,
you could use a modified version of Gnulib that runs gcc -E all
the time, for debugging.

The hydra output did suggest one fix, though.  I pushed the following into
gnulib.  The patch is needed, even if it doesn't fix your bug.
Does it help?
