Hi,

I've just noticed this warning when building on Debian 12:

In file included from /usr/lib/llvm-14/include/llvm/Analysis/ModuleSummaryAnalysis.h:17,
                 from llvmjit_inline.cpp:51:
/usr/lib/llvm-14/include/llvm/IR/ModuleSummaryIndex.h: In constructor ‘llvm::ModuleSummaryIndex::ModuleSummaryIndex(bool, bool)’:
/usr/lib/llvm-14/include/llvm/IR/ModuleSummaryIndex.h:1175:73: warning: member ‘llvm::ModuleSummaryIndex::Alloc’ is used uninitialized [-Wuninitialized]
 1175 |       : HaveGVs(HaveGVs), EnableSplitLTOUnit(EnableSplitLTOUnit), Saver(Alloc),
      |                    

cat /etc/debian_version 
12.1

Regards
Daniel
