Firstly, sorry for the delay! On Mon, Apr 8, 2019 at 4:52 AM Juan Pablo Hierro Álvarez <hierro@unizar.es> wrote:
Dear sirs,
This is my first mail to this list and do not expect to remain very active.
I was running a Fedora 29 machine and tried to install cmucl 21d.
Binaries worked without trouble. However, I decided to try and bootstrap the system, only to head into open issue #68.
https://gitlab.common-lisp.net/cmucl/cmucl/issues/68
I write this message because I think that I have found a work-around:
In file cmucl/src/lisp/Config.x86_common
I had to exchange the line
CFLAGS += -O2
with
CFLAGS += -O1
Thanks for looking into this. I can confirm that -O1 works with gcc 8.3.1 on my Fedora system. This is a reasonable workaround. We probably won't lose too much this way. I think the only possibly heavy usage of C code is for the garbage collector.
That is to say, latest versions of the gcc compiler are only able to produce a working cmucl lisp binary with an optimization level up to -O1.

The proposed replacement of gcc by clang *(Commit 82bf2c72) *worked too. By the way, clang apparently works fine with optimization -O3.
Probably not a whole lot to be gained by using -O3, but I also didn't test this.
-----------
Notwithstanding the previous assertions, I run tests and all of them worked but for "issue.45".
Failed tests: (ISSUES-TESTS::ISSUE.45) | Failed Form: (GET-OUTPUT-STREAM-STRING ISSUES-TESTS::S) | Expected "ls-link " but saw "/usr/bin/env: 'test-tmp/ls-link': No such file or directory
Hmm. I don't have this problem. I'll look into it later.

Of course, there were no test-tmp directory in my file system. Is this an expected behaviour or should the tests have created the needed directories and files?
Yours faithfully,

Juan Hierro.
