So, here's the image for the reproduction:
http://czg.harmless.hu/emacs/qemu-28308.gz
You can start it with:
qemu-system-aarch64 -m 4096M -cpu cortex-a57 -M virt \
-accel tcg,thread=single \
-bios QEMU_EFI.fd -serial telnet::4444,server
-nographic \
-drive if=none,file=${image},id=hd0,format=raw \
-device virtio-blk-device,drive=hd0 \
-device e1000,netdev=net0 \
-netdev
tap,id=net0,ifname=tap0,script=/tank/rpi3/build/qemu-ifup.sh
adjust the $image, and the last line for the networking, it just sets
the IP address on the host device:
ifname=$1
ifconfig ${ifname} inet 10.219.14.254/24
The root password is "foobar", has an sshd running, so you can later log
in, tramp into it,etc.
Steps to reproduce the build failure:
cd /usr/ports/editors/emacs-devel
setenv CFLAGS "-O0 -glldb"
setenv CXXFLAGS "-O0 -glldb"
make -DTRYBROKEN DISABLE_VULNERABILITIES=yes build
The ports tree extracts the source under and does the actual build under
work/, you will find it all there.
Also, just in case, I've checked out the emacs source from github under
/root/emacs/, to save you some time if that's needed.
If you would like to test the build from a different checkout in ports,
just update /usr/ports/editors/emacs-devel/Makefile:
1) update the GH_TAGNAME
2) rm distinfo
3) make makesum
4) rm -rf work
5) then you can start the build again
I hope this helps.
Best regards,
Gergely
