- Subject: Bug in definition of LUAL_BUFFERSIZE
- From: Tom Sutcliffe <tomsci@...>

Hi list,
Here's a fun bug in 5.3's default luaconf.h definition of LUAL_BUFFERSIZE:
#if defined(LUA_FLOAT_LONGDOUBLE)
#define LUAL_BUFFERSIZE 8192
#else
I believe it should read:
#if LUA_FLOAT_TYPE == LUA_FLOAT_LONGDOUBLE
#define LUAL_BUFFERSIZE 8192
#else
Under the new way of defining types in luaconf.h, LUA_FLOAT_LONGDOUBLE will be defined regardless of what type is actually configured. This just stung me on an embedded project where the entire stack was less than 8KB so upgrading to Lua 5.3 made everything immediately blow up!
Cheers,
Tom
