Duplicate definition error involving symbols for global arrays and pointers in C native Kernel

[anutosh491]

Check these examples

This corrupts the whole session as such and needs a kernel restart !

Works perfectly fine for the wasm kernel

Probably a clang-repl error when run in C mode

anutosh491@Anutoshs-MacBook-Air bin % ./clang-repl --Xcc=-x --Xcc=c --Xcc=-std=c23
clang-repl> #include <stdio.h>
clang-repl> char *p;
clang-repl> printf("ok\n");
error: Duplicate definition of symbol '_p'

Opening an issue on llvm after I try again with the latest build locally !

tagging y'all if you might have seen this before (fortunately works perfectly fine with the wasm kernel)

That’s something we need to fix in clang-repl. Somehow we are emitting multiple times given definition.

[anutosh491]

Yupp as my comment says, I'll quickly check with the latest build and report upstream and investigate more !
