Warning while compiling 19beta1 - Mailing list pgsql-bugs

Hi,
fetched newest git head (commit
f0aedc7cb0ed82d4cca48332dc0852c767514558), and compiled it.
When doing so I got:

llvmjit.c: In function ‘llvm_split_symbol_name’:
llvmjit.c:1065:27: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
 1065 |                 *funcname = strrchr(name, '.');
      |                           ^

Generally I wouldn't care, but pg normally compiles without warnings, so this one stuck out :)


My system is Linux/Ubuntu 26.04. Interesting (?) packages:
