GNU F95 version 4.2.0 20060618 (experimental) (i686-pc-linux-gnu)
compiled by GNU C version 4.2.0 20060618 (experimental).
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096

Note that it seems necessary that the subroutine be called both from the
program and the contained procedure.
