Thank you for the analysis and the patch! It fixes the issue for me too.

Yeah, I also noticed that, and a simple grep-based script with a little
eyeballing discovered one similar Assert usage:
void
llvm_split_symbol_name(const char *name, char **modname, char **funcname)
{
...
*funcname = rindex(name, '.');
(*funcname)++; /* jump over . */
*modname = pnstrdup(name + strlen("pgextern."),
*funcname - name - strlen("pgextern.") - 1);
Assert(funcname);
May be it's worth to fix it in passing.
Best regards,
Alexander
