I stumbled upon a C file (well, I wrote it :) that trips the parser for the symbol table. For a while, number literals in C++ and C can be partitioned visually by using single quotes, e.g., `0b0000'0000` - so-called digit separators. This has finally been standardized in C23 (and previously in C++14).

I have found that in case of initializing a subelement (e.g., a struct within an array of structs, i.e., within a second pair of curly braces), the quotes are not handled correctly. If the quotes appear in pairs it's fine which makes me think it tries to match them to find character literals.

See below for a demo. Notice how the function `test_func` vanishes from the symbol table depending on the amount of `'`s.


I have only tested this with Geany 1.38. Here is the test case for easy verification:

struct something arr[] = { { 0b0000'0000 }, };

void test_func(void) { }
