v.reflection does not populate when compiled as a shared library (-shared)

[jcweaver997]

Describe the bug

v.reflection does not populate when compiled as a shared library (-shared)

Everything is empty, here is an example:

This causes "some" print formatting to fail for gdextension. Simple values like number types work fine, but printing structs does not. All types still have non-zero T.idx's but the reflection tables are empty.

Reproduction Steps

To produce this, I was working on vgdextension. Godot loads the shared library and calls the entry point function. As this requires you to create a shared library and load it dynamically, its a bit harder to get setup. This can be easily reproduced using the example for jcweaver997/vgdextension, importing v.reflection, and trying to get a type or list the types. String formatting a struct will cause the program to crash.

Expected Behavior

v.reflection tables to be populated and no crashing when string formatting a struct

Current Behavior

v.reflection tables are empty and crashes are experienced when string formatting a struct

Possible Solution

For windows we have a _vinit_caller fn which is calleld on

It must be called to fill the reflection data as a non-shared one.

Thanks @felipensp, that makes sense. Everything appears to work using:

fn C._vinit(int, voidptr)

and calling this in the entrypoint:

C._vinit(0, unsafe{nil})
