Hi all, please find attached a fix for the recently introduced regression when allocating arrays with an intrinsic function for source=. The patch addresses this issue by using gfc_conv_expr_descriptor () for intrinsic functions.
Bootstraps and regtests ok on x86_64-linux-gnu/F20. Ok for trunk? Regards, Andre -- Andre Vehreschild * Email: vehre ad gmx dot de
