--- Comment #5 from Kirill Yukhin <kyukhin at gcc dot gnu.org> --- A bug in fortran's IO RT has emerged during 21 Apr 2016, between r222254 and r222292; looks like it's caused by the same revision –r222271 (libgfortran/io/list_read.c ), which probably just triggers another hidden bug. Trying two builds (as of 21 and 22 Apr ): $ gfortran-20160421 -O0 T.f90 -static $ ./a.out res, (1) == 1 ! ### Ok ^^^^^^^^ $ gfortran-20160422 -O0 T.f90 -static $ ./a.out res, (1) == 80 @p¼B ### FAIL – garbage is read in ^^^^^^^^
