[wasm] LLVM ERROR: LEB is outside Varint32 range

[merlinsun]

Hi,
For this case, emcc crashes when compiling this file.
I feel sorry it is not easy to reduce.

$ emcc -w test.c
LLVM ERROR: LEB is outside Varint32 range
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

I have a similar issue when linking an WASM executable, only for me it happens when llvm-objcopy is called by the linker. Anyone know how to solve this?

I can reproduce it by just executing the command at the bottom.

Could you attach a copy of the wasm file?
