It has been reported that PL/Tcl built on macOS with GCC >=11 crashes. The reason is that there is a hash_search() function in the operating system's libraries, and that ends up being called instead of the one in postgres. This has something to do with how the linker resolves references between the various possibilities it has been given, and somehow something changed that it is now picking that one in this configuration. We found that removing the -lc from the link command line fixes this problem. The -lc was introduced a long time ago in commit e3909672f12e0ddf3e202b824fda068ad2195ef2, and we think the reasons might be obsolete, so we decided that we'll try to just remove it and see if any problems arise.
