GDB backtrace when running /usr/lib64/libreoffice/programs/oosplash
Fresh install of LibreOffice 7.5.3.2 on Gentoo. When built with clang and lto,
launching the /usr/bin/libreoffice script or /usr/lib64/libreoffice/oosplash
hangs indefinitely, whilst running /usr/lib64/libreoffice/soffice.bin works.
I'm attaching a gdb backtrace. Other relevant elements:
clang --version
clang version 16.0.5
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/lib/llvm/16/bin
Configuration file: /etc/clang/clang.cfg
/etc/clang/clang.cfg
# This configuration file is used by clang driver.

/etc/clang/gentoo-common.cfg
# This file contains flags common to clang, clang++ and clang-cpp.

@gentoo-hardened.cfg
# bug #870001
-include "/usr/include/gentoo/maybe-stddefs.h"
/etc/clang/cfg/gentoo-runtimes.cfg
# This file is initially generated by sys-devel/clang-runtime.
# It is used to control the default runtimes using by clang.
--rtlib=libgcc

-fuse-ld=bfd
/etc/clang/gentoo-gcc-install.cfg
# This file is maintained by gcc-config.
# It is used to specify the selected GCC installation.
--gcc-install-dir="/usr/lib/gcc/x86_64-pc-linux-gnu/12"
/etc/clang/gentoo-hardened.cfg
# Some of these options are added unconditionally, regardless of
# USE=hardened, for parity with sys-devel/gcc.
-fstack-clash-protection
-fstack-protector-strong
-fPIE
-include "/usr/include/gentoo/fortify.h"
strace -p -f on the libreoffice process doesn't provide any output after
process X attached.
Relevant Gentoo bug https://bugs.gentoo.org/907905 (a little bit convoluted in
the report, one has to admit).
Let me know if I can give any additional information.
