I think I found the problem. The "object name" comes from a Mapi handle,
which is closed. Hence the pointer is invalid. I now properly copy the
string, which should solve the issue.
A few questions remain:
- How can Solaris print a value
- How/why can the parser accept the garbage
I checked in my fix on the Stable branch. Mtest successfully completes
here on my system.

Solaris shows an interesting behaviour. In contrast to all other
platforms, on Solaris a value is printed (io.print), containing "bla".
While this is certainly wrong (there is no output), the problematic part
here is that the io.print should never be called, since an exception is
thrown.

The test fails since Wednesday June 4 2008, i.e., after checkins on
Tuesday June 3 2008.

garbage can be passed as argument (does the parser even accept that?),
if:
str RMTget(MalBlkPtr mb, MalStkPtr stk, InstrPtr pci) {
str conn, ident, tmp;
ident = (str)getArgValue(stk, pci, 2);
if (isIdentifier(ident) < 0)
throw(ILLARG, "remote.get", "identifier expected, got '%s'",
ident);
/* perform the get */
rethrow("remote.get", tmp, RMTinternalget(c->mconn,
ident, &stk->stk[getArg(pci, 0)]));
ident in the above code is valid for isIdentifier(), but in fact garbage.

This is the relevant code snippet:
str RMTserveget(MalBlkPtr mb, MalStkPtr stk, InstrPtr pci) {
int i;
str name;
name = (str)getArgValue(stk, pci, 1);
i = findVariable(mb, name);
if (i < 0)
throw(MAL, "remote.serveget", "no such object '%s'", name);
either, garbage was given as argument, or retrieving the first argument
(like this) doesn't work (any more).
