RPG compiler bad behaviour with *VARSIZE and litterals

when a prototype declare size 1 option(*varsize),
when the program uses the prototyped call passing a litteral parameter, even if the litteral is long, the compiler has no care of *VARSIZE, and truncates the litteral at size 1.
the result is a memory corruption

rpg compiler does not say anything (no error, no warning). At least, add a warning message in the compilation list.

the best option is to respect the litteral to send to the called.

Use Case:

pmr 73880,650,706,
opened 2015-10-09, solved 2016-09-19.
try to read LICPGM list.

346 days required to find the reason of the error !

    IBM does not intend to change the behavior for OPTIONS(*VARSIZE) and CONST, so this request is being closed.

    OPTIONS(*VARSIZE) is intended to allow parameters to be passed that are smaller than the prototype indicates. The length of a parameter defined with OPTIONS(*VARSIZE) and CONST should be the longest length expected for the parameter.
