Julien, could you maybe try downgrading to the older binutils version, and seeing what went wrong ? As said on irc, the likely solution here would be to disable the alpha native compilers until the solution is found.

Hi, Starting from ocaml version 3.08.3-8, ocamlopt.opt doesn't work at all on alpha. Since 3.08.3-7 built fine, I think this is a toolchain issue. 3.08.3-7 was built with gcc-4.0 4.0.1-4, binutils 2.16.1-2 and libc6.1-dev 2.3.5-3, while 3.08.3-8 was built with gcc-4.0 4.0.1-6, binutils 2.16.1cvs20050902-1 and libc6.1-dev 2.3.5-5. Does anyone know of an alpha-related change in the toolchain between these versions, which could have caused this? Unfortunately, I wasn't able to get a meaningful backtrace with gdb (I only know that the segfault occurs at program startup).

Just build with > ocamlopt. You might even do this everywhere, it's just a bit slower. Since ocamlopt.opt is itself built as nativecode with ocamlopt, it the former is broken it doesn't bode well for the fiability of the later.

The bug actually *is* important and I do not really intent to make it "serious". I'm not sure about the right way to recompile geneweb with bytecode on alpha. Actually, this is done in debian/rules with: PACKAGE=geneweb WAY=$(shell if [ -f "/usr/bin/ocamlc.opt" ]; then echo "opt"; \ else echo "out";\ fi) Then $WAY is used to compile one way or another. I guess that adding a specific test for Alpha architecture here would be the Right Hack. Something like: DEB_HOST_ARCH_OS := $(shell dpkg-architecture -qDEB_HOST_ARCH_OS) ifeq ($(DEB_HOST_ARCH_OS),alpha) WAY=out else WAY=$(shell if [ -f "/usr/bin/ocamlc.opt" ]; then echo "opt"; \ else echo "out";\ fi) endif -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

This used to work, since we didn't update ocaml since sarge was out, so i guess it is probably a breakage introduced by a binutils upgrade or new gcc or something. Someone from the alpha porting team needs to have a look, but since they don't even find time to work on the upcoming kernel packages, ... Anyway, ocaml 3.09 should be out RSN, and we will be upgrading all our packages to it, so i wouldn't lose time for etch/sid 3.08.3 builds.
