Hi folks,
I recently wrote a blog post on LuaJIT's GC64 mode, especially in the
context of OpenResty:
https://blog.openresty.com/en/luajit-gc64-mode/
it's a very good summary. I've fouind GC64 to be inmensely more
stable, and hope it becomes the default everywhere.
about the GDB tools, i got most of the TValue inspecting functions
working in my fork; the biggest problem is getting a usable backtrace
with local variable names. In most cases i just relied on a simple
dump of the Lua stack. In fact, after switching to GC64 the amount of
coredumps i had to analyse reduced so much that i didn't get enough
examples (or motivation) to really fix the backtraces.
