Tobi,
I won't be able to look into this problem until late November. Yes,
I'm still on a boat in the Gulf of Mexico. Valgrind's output suggests
that the problem is within the MPFR library. At least, I know I never
used mpfr_set4 or mpfr_round_raw_generic.

This is an issue in mpfr, and is fixed by a newer libmpfr. I didn't find
anything pertaining to this in mpfr's ChangeLog's, but the failure disappeared
after installing the current mpfr, and the code in gfortran is definitely right:
- I verified that all mpfr variables are initialized before being set in
gfc_convert_real ()
- I verified that the string buffers passed to mpfr_set_str are set to the right
lengths and correctly zero-terminated
I'm closing this as WONTFIX, if someone disagrees, feel free to reopen.
