"size of C type is unknown or too large" #31

Open Calandiel opened 2 years ago

Calandiel commented 2 years ago

I just got that error message. It's not really clear. Perhaps it should mention that size limit? I was trying to serialize ~100 megabytes of cdata (VLAs to be more precise) I tried to follow the stack trace but it wasn't clear to me what exactly happened. In either case, here it is:


engine/bitser.lua:228: size of C type is unknown or too large

That's unfortunate. Could you help me out by creating a minimal reproducible example? That would allow me to figure out if there is a way to fix this or at least figure out the exact limits so it can be documented.
