I have encountered some odd behaviour in looking at vararg2.mod.

Compiled in default 32-bit mode, the calls fail:

[~/opt/gm2/testsuite/2023-03-29]=> gm2  vararg2.mod cvararg.o -lnsl -lsocket
[~/opt/gm2/testsuite/2023-03-29]=> ./a.out
parameter is hello world and length 0

Compiled in 64-bit mode, the calls pass:

[~/opt/gm2/testsuite/2023-03-29]=> gm2 -m64 vararg2.mod cvararg.o -lnsl 
-lsocket
[~/opt/gm2/testsuite/2023-03-29]=> ./a.out
parameter is hello world and length 11
parameter is hello and length 5
parameter is /etc/passwd and length 11

I have no explanation at the moment.  (Trying to debug the 32-bit does 
not work -- the a.out calls 64-bit gm2 libraries -- and the 64-bit 
binary crashes gdb.  So work in progess. #6-)

Sincerely,
john
