Setup:
Compiled with a recent version of Clang (I used Clang 18.1.3) with LLVM 18:
|
# llvm-17-linker-tools installs /usr/lib/llvm-17/lib/LLVMgold.so, which is needed for compilation, and LLVMgold.so is no longer included in LLVM 18
|
sudo apt install clang llvm-18 llvm-18-linker-tools llvm-18-runtime llvm-18-tools llvm-18-dev libstdc++-14-dev llvm-dev llvm-17-linker-tools
|
sudo ln -s /usr/lib/llvm-17/lib/LLVMgold.so /usr/lib/llvm-18/lib/LLVMgold.so

A UBSAN suppresion filter function:show_status_array was added for this bug. Any issue with show_status_array anywhere in the stack will be filtered. This is a limitation of UBSAN suppression filtering. The filter will be removed once the bug is fixed.
bnestere can I get a review on these two PRs that correct this please:
Note that for 11.4+ the call to function differs:
