C and CUDA files in `compile_commands.json` are misinterpreted as C++ files

Environment

• OS and Version: Ubuntu 24.04
• VS Code Version: 1.99.0
• C/C++ Extension Version: 1.24.5

Bug Summary and Steps to Reproduce

While editing a .c file, vscode shows this warning for the code uint8_t *ptr = malloc(size):

a value of type "void *" cannot be assigned to an entity of type "uint8_t *" (aka "unsigned char *")C/C++(513)

I believe that's a C++ warning that should not happen in a C program.

I have a compile_commands.json that does provide the compile command for that specific file and it produces no warning. The command starts with ccache cc ... with cc symlink to /usr/bin/gcc.

Hi @xclaesse . Thanks for reporting this. It looks like 1.24.5 has a regression related to C and CUDA source files in compile_commands.json being interpreted as C++. We have a fix in progress that should go into our next prerelease.
