This is a big endian issue (at least for ppc64 that is BE)
I verified that no such failure for x86_64 or ppc64le that are LE.

[aoh]

Thanks. I haven't had access to LE machines for a while, so quite possbile that endianess issues have turned up at some point.

Could you also attach the last few lines of strace owl-lisp-0.1.10/bin/vm owl-lisp-0.1.10/fasl/init.fasl -O2 -o radamsa.c rad/main.scm? Seems odd that owl can build itself, but not radamsa.

[aoh]

BE, even. Bug reproduced in Debian running on Qemu/PPC.

There was indeed an endianess bug in tag check when opening files. Fix is now in owl, but I don't have time to check it now, since the build takes a long time on my emulated machine. If you can, you can verify the fix as follows:
$ cd radamsa
$ git clone https://github.com/aoh/owl-lisp.git
$ cd owl-lisp
$ make
$ cd ..
$ owl-lisp/bin/ol -O2 -o radamsa.c rad/main.scm
$ make
$ echo 'HAL 9000' | bin/radamsa -o tmp/rad-%n.hal -n 10 -v && echo ok

[aoh]

Build passed in vm. Assuming fixed. Reopen if the issue persists.

Thanks for the bug.

[michelmno]

Thank you for the correction.
I verified on my ppc64 guest the fix with your detailed steps and that succeeded.
My only small comment is that there are still compilation warning, but not a critical problem.

Vm() prototype now has argument types in owl, so the warning won't turn up in the next release.
