Research direction

Start with the linked non-working example and reproduce the AccessViolationException while parsing <type_traits>; inspect Parser::WalkAST() at the failure point. Compare the two linked fixes to understand the templated inheritance and template-alias cases, and consider the issue done when the examples parse without the exception.

Written by the indexing model from the issue text.

Description

bug

When the file type_traits of the standard library is included (#include <type_traits>), the parses throws an AccessViolationException while inside the void Parser::WalkAST() function.

This issue has to do whit the C++ standard library deriving a templated class from another templated class and specializing at least one of the base class' arguements with a template alias.

Following there are a not working example and two fixes:

  • not working: here
  • first fix: here
  • second fix (more interesting since it's only without the template alias): here
