Bug ID: 42478
Summary: building cross-tools on OpenBSD results in crash
Product: clang
Version: 8.0
Hardware: PC
OS: OpenBSD
Status: NEW
Severity: normal
Priority: P
Component: Driver
Assignee: unassignedclangb...@nondot.org

crash log excerpt
I thought it would be a good idea to rebuild cross-tools because of LLVM
version bump
but - with recent src - I'm unable to do so:
$ doas make -f Makefile.cross TARGET=${target} CROSSDIR="${destdir}"
cross-tools
fails with:
aarch64-unknown-openbsd6: error: unable to execute command: Segmentation fault
(core dumped)
With updated /etc/mk.conf:
DEBUG=-gline-tables-only
(I think it’s unused for clang but disables stripping during installation?)
and src/gnu/usr.bin/clang/Makefile.inc:
CPPFLAGS+= -DNDEBUG -gline-tables-only
(I think it’s similar to what cmake RelWithDebugInfo does.)
I was eventually able to get debug symbols. More details in attached files.
I reproduced this crash on other machine.
If anyone would like to give it a quick try, then please just follow „Setup”
