We're asking for a QImode subword at offset 0 of
(mem/s/j:BLK (plus:DI (reg:DI 112)
(reg:DI 96 [ D.1297 ])) [0 S32 A8])
in expansion of
(*D.1297)[S.20D.1298] = D.1302
4.0 fails differently:
gcc40-g/gcc> ./f951 -quiet ../../gcc41-g/gcc/t.f90
../../gcc41-g/gcc/t.f90: In function 'MAIN__':
../../gcc41-g/gcc/t.f90:8: internal compiler error: in gfc_conv_function_call,
