size_t not recognized correctly

[tregua87]

Hi, I reopen this issue.

I am encountering the same problem. For some files/headers, the libclang misinterpret size_t type.

I am in an Ubuntu 20.04 (Dockerized) with libclang==14.0.6 (installed from pip).

I made a minimal example here. You should just unzip and run ./sizet_error.py

To note that clang-12 seems to get the correct AST.

     tu = index.parse(tmp_file, args=[f"-I{include_folder}"])
+    for diag in tu.diagnostics:
+        print(diag)

You will see that there are some errors during parsing:

./min.cc
././aom/aomcx.h:19:10: fatal error: 'aom/aom.h' file not found
