To reproduce, on a 32-bit system:
./configure ... --with-wide-int
make
cd test/automated
make
This causes the cl-lib-tests to fail in this innocent check:
(ert-deftest cl-lib-test-first ()
(should (null (cl-first '()))) <<<<<<<<<<<<<<<<<
The error is "Invalid function ((nil))".
The same test runs fine in a 32-bit build with 32-bit ints.
While digging into this, I found out that if I compile cl-lib-test.el
with an Emacs executable that doesn't use wide ints, the test
succeeds. So I compared the .elc files, and they indeed differ.
Moreover, by comparing the *.elc files in the entire Emacs tree, I
found 3 files that differ: cl-generic.elc, srt-wy.elc, and one file in
Eshell whose name I don't remember.
Focusing my attention on cl-generic, which might explain why
cl-lib-tests fails, how can I debug this? Would presenting
disassembly of a part of the byte code where I see differences help
someone to come up with ideas? Are there any other directions to
investigate this?
Did anyone run the test suite successfully in such a 32-bit build? Do
all the *.elc files come out identical to a "normal" 32-bit build?
TIA
