I can confirm the segfault with 4.8, but I don't see it with trunk. However, also with trunk one gets some valgrind errors: ==13526== Conditional jump or move depends on uninitialised value(s) ==13526== at 0x4F0E687: _gfortran_transfer_character (in /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0) ==13526== by 0x400806: MAIN__ (c0.f90:8) ==13526== by 0x400835: main (c0.f90:8) I don't directly see why the code would be invalid.
