It happened because gfortran >= 4.6 uses this function and GDB cannot
reverse-step-over such jmp-only function.

(gdb) disass _gfortran_transfer_real_write
Dump of assembler code for function _gfortran_transfer_real_write:
   0x00007ffff7b9f930 <+0>:    jmpq   0x7ffff7ae0a30
<_gfortran_transfer_real@plt>
End of assembler dump.
