Unless I'm reading LLDB incorrectly, it says m->charpos = 0 > for that frame. If some code does that, it's a bug, and we should try to find it. I'm just astonished that we have such bugs in such a basic infrastructure. The reason I asked about memory problems is that m->bytepos is reasonable. So it isn't like some code stored the invalid zero buffer position there, it's something that corrupted the marker. I thought about GC or free'd memory, but that is at odds with the valid buffer pointer and a reasonable bytepos. So strange... And why you are the only one who sees these problems? A hardware problem can nicely explain all of those.
