Yes, it is beginning to look like some sort of compiler issue.
FWIW, I found a Sparc Solaris machine here that has an XEmacs 21.1.11
on
it. It displays the same problem. Evaluating (let (3) t) is
sufficient. Here is its installation info. That box has gcc 2.95.3
now, but there's no telling what version it was when this XEmacs was
built.

Where should the build process find the source code?

What installation prefix should install use? /usr/local
What operating system and machine description files should XEmacs use?
`s/sol2.h' and `m/sparc.h'
What compiler should XEmacs be built with? gcc -mcpu=supersparc -O2
Should XEmacs use the GNU version of malloc? yes
Should XEmacs use the relocating allocator for buffers? yes
FWIW², I also have 21.1.11. BUT, I do not see this problem in 2.1.11.
I do see this problem in 21.4.6. I have gcc 2.95.2.

21.1.11 stuff - no problem evaling (let (x 3) ...)
