Hi

on fresh Fedora 38, I cannot to run regress tests

+ERROR:  could not load library "/home/pavel/src/postgresql.master/tmp_install/usr/local/pgsql/master/lib/llvmjit.so": /home/pavel/src/p

There is lot of compile warnings

Looks like the new LLVM 16.  I'll try to look at this again next week.
In the meantime you could try using 15.

I've become entirely desensitized to seawasp failing, which is probably
a bad thing, but today I happened to look at it and discovered that
its compiler has been dumping core for some time now:

clang: /home/fabien/llvm-src/llvm/lib/Transforms/Scalar/SROA.cpp:1745: llvm::Value*
getAdjustedPtr({anonymous}::IRBuilderTy&,const llvm::DataLayout&, llvm::Value*, llvm::APInt, llvm::Type*, const
llvm::Twine&):Assertion `Ptr->getType()->isOpaquePointerTy() && "Only opaque pointers supported"' failed. 
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace,
preprocessedsource, and associated run script. 
Stack dump:
0.    Program arguments: /home/fabien/clgtk/bin/clang -Wno-ignored-attributes -fno-strict-aliasing -fwrapv
-fexcess-precision=standard-Xclang -no-opaque-pointers -Wno-unused-command-line-argument

-ostrftime.bc strftime.c 
1.    <eof> parser at end of file
2.    Optimizer

Seems like we ought to look into that, and report it as requested.
