Bug 17833 – compiling dmd on x86 linux fails

Created attachment 1658 log of build on i686 following the steps here: https://wiki.dlang.org/Building_under_Posix The build of dmd fails with a segfault at: > cd "$srcdir/druntime" > make -f posix.mak The full log is attached. The steps are: > git clones/checkouts > cd "$srcdir/dmd" > make -f posix.mak AUTO_BOOTSTRAP=1 MODEL=32 > cd "$srcdir/phobos" > make -f posix.mak MODEL=32

I am having the same problem when trying to build dmd 2.075.1 with the dmd-cxx branch version at commit 7f7dd837f1cf92e3fd51fabbb95868b4b297ad37 as bootstrap dmd. The error message is: gmake[2]: *** [posix.mak:147: import/core/sync/barrier.di] Segmentation fault Switching back to 2.067.1 as bootstrap compiler makes it work again. @ibuclaw: Do you happen to know what the problem might be?

Bumping this issue, since this is triggering the removal of this package from the archlinux32 repos.

Hmm building DMD on Linux 32 works on our CIs (e.g. https://auto-tester.puremagic.com/platform-history.ghtml?projectid=1&os=Linux_32), so I'm not sure what this is related to. The dmd-cxx branch was just an experiment, but it was never fully finished. Do you still get a segfault when using AUTO_BOOTSTRAP=1? (since 2.081 at least 2.074 is required to build DMD)

Created attachment 1708 installed packages

still fails for me. I ran: > mkdir dlang > cd ~/dlang/ > git clone https://github.com/dlang/dmd > git clone https://github.com/dlang/druntime > git clone https://github.com/dlang/phobos > git clone https://github.com/dlang/tools > cd ~/dlang/dmd > make -f posix.mak -j8 AUTO_BOOTSTRAP=1 > cd ~/dlang/phobos > make -f posix.mak -j8 inside an archlinux32 virtual box. See above for a list of installed packages on that box.

We have an archlinux32 image for vagrant which you can use to reproduce the issue. The commands are: > mkdir arch32-builder > cd arch32-builder > vagrant init archlinux32/archlinux32 > vagrant up > ssh [email protected] -p 2222 -o StrictHostKeyChecking=Off -o IdentityFile=.vag$ >> sudo pacman -Syu base-devel curl git make libcurl-gnutls >> sudo reboot > ssh [email protected] -p 2222 -o StrictHostKeyChecking=Off -o IdentityFile=.vag$ >> mkdir dlang >> cd dlang/ >> git clone https://github.com/dlang/dmd >> git clone https://github.com/dlang/druntime >> git clone https://github.com/dlang/phobos >> git clone https://github.com/dlang/tools >> cd ~/dlang/dmd >> make -f posix.mak -j8 AUTO_BOOTSTRAP=1 >> cd ~/dlang/phobos >> make -f posix.mak -j8 (fails with segfault)

Thanks that works in reproducing the segfault :/ Command Line: ../dmd/generated/linux/release/32/dmd -conf= -c -o- -Isrc -Iimport -Hfimport/core/sync/barrier.di src/core/sync/barrier.d (gdb) bt full #0 0x00861f61 in _d_dso_registry () No symbol table info available. #1 0x007b53cf in ?? () No symbol table info available. #2 0x0087d97b in __libc_csu_init () No symbol table info available. #3 0xb7aecfd3 in __libc_start_main () from /usr/lib/libc.so.6 No symbol table info available. #4 0x0065d601 in _start () No symbol table info available. However, there's a workaround: Instead of using AUTO_BOOTSTRAP=1, you can use make -f posix.mak -j8 HOST_DMD=ldmd to compile dmd. With this druntime and phobos compile fine. So I guess it's just an issue that the release binaries aren't fully working with 32-bit anymore?

thanks for your prompt reply - the workaround works :-)

Still ?
