I cannot reproduce this issue locally (00d8ea3). Can you share the config to reproduce it?

git clone https://github.com/LibreOffice/core
cd core
export CC=<path to clang>
export CXX=<path to clang++>
./autogen.sh
make -j

[printfdebugging]

@dtcxzyw I used the following autogen.input file

--enable-dbgutil
--without-java
--without-doxygen
--enable-ccache
--enable-kf6
--enable-compiler-plugins
--with-help=html
--with-system-libxml=no
CC=clang
CXX=clang++

It only happened once, after which it was working fine.

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

Can you attach preprocessed source?

Can you attach preprocessed source?

I don't have it at hand, and in the last (more than 2 months), it never happened again. I am afraid that I don't have anything else to add to this ticket than just "oh it happened and the message said report it, so I opened a ticket". Back then I didn't think/know about saving the preprocessed source. You can close the ticket, thanks!
