[mingodad]

Did you check existing issues?

• [X] I have read all the tree-sitter docs if it relates to using the parser
• [X] I have searched the existing issues of tree-sitter-c

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

tree-sitter 0.20.9 (8759352542e298a537ff7d96d74b362d9011684b)

Describe the bug

#define STR "string"

    const char *str = "The " STR "\n";
}
