Access violation while trying to parse a simple test.h file.

[Jerem2360]

I was trying to parse the following "test.h" file:

void foo() {}

which I created for testing purposes.

The directory tree is:

project
    - header_parser.py
    - test.py
    - test.h
    - tools
        - gcc.exe
        - castxml.exe

test.py looks like this:

import header_parser

parser = header_parser.HeaderParser()
data = parser.parse("test.h")
print(data)

and header_parser.py looks like this:

import pygccxml
import pygccxml.utils
import pygccxml.parser


class HeaderParser:
    def __init__(self):
        genpath, genname = pygccxml.utils.find_xml_generator(search_path="tools")

        self._config = pygccxml.parser.xml_generator_configuration_t(
            xml_generator_path=genpath,
            xml_generator=genname,
            compiler_path="tools/gcc.exe",
        )

    def parse(self, *filenames: str):
        declarations = pygccxml.parser.parse(list(filenames), self._config)

        return pygccxml.declarations.get_global_namespace(declarations)

However, running test.py with a mere python 3.13 installation and no arguments produces this output:

And indeed, hex(3221225477) is 0xc0000005 which is ERROR_ACCESS_VIOLATION on windows.

Hi

That's probably better asked on the castxml repo.
But there might be some things that can be tested here: https://www.auslogics.com/en/articles/fix-access-violation-at-address
I did not test this, it's an issue with your Windows setup.

Hello,
I have submitted an issue on the CastXMLSuperBuild repo. I have tried many generic windows fixing tips without success.
