OK. But it makes no sense trying it on a target that does not have malloc().

For such targets, the inferior call attempt should fail when strings are passed as arguments with some meaningful message (maybe that is what happens, I haven't seem the gdb.log).

Do you happen to know why was it important to test with a test program that does not call malloc() itself?
