erc_iterStart (through alias s2): erc_iterStart(s2)
An externally-visible object is modified by a function, but not listed in its
modifies clause. Use -mods to suppress message.

erc.c:34,9: Operands of == are abstract type (eref): tmpc->val == er
An abstraction barrier is broken. If necessary, use /*@access @*/ to
allow access to an abstract type. Use -abstract to suppress message.
