>> BUG: "lastline" was not reset on function entry, so debug information
>> started only in the 2nd line of a function.



--- Version 3.1 alpha

** lua.c
Thu Jan 15 14:34:58 EDT 1998
>> must include "stdlib.h" (for "exit()").

** lbuiltin.c / lobject.h
Thu Jan 15 14:34:58 EDT 1998
>> MAX_WORD may be bigger than MAX_INT
(by lhf)

** llex.c
Mon Jan 19 18:17:18 EDT 1998
>> wrong line number (+1) in error report when file starts with "#..."

** lstrlib.c
Tue Jan 27 15:27:49 EDT 1998
>> formats like "%020d" were considered too big (3 digits); moreover,
>> some sistems limit printf to at most 500 chars, so we can limit sizes
>> to 2 digits (99).

** lapi.c
Tue Jan 27 17:12:36 EDT 1998
>> "lua_getstring" may create a new string, so should check GC

** lstring.c / ltable.c
Wed Jan 28 14:48:12 EDT 1998
>> tables can become full of "empty" slots, and keep growing without limits.

** lstrlib.c
Mon Mar  9 15:26:09 EST 1998
>> gsub('a', '(b?)%1*' ...) loops (because the capture is empty).

** lstrlib.c
Mon May 18 19:20:00 EST 1998
>> arguments for "format" 'x', 'X', 'o' and 'u' must be unsigned int.



--- Version 3.1

** liolib.c / lauxlib.c
Mon Sep  7 15:57:02 EST 1998
>> function "luaL_argerror" prints wrong argument number (from a user's point
of view) when functions have upvalues.

** lstrlib.c
Tue Nov 10 17:29:36 EDT 1998
>> gsub/strfind do not check whether captures are properly finished.
(by roberto/tomas)

** lbuiltin.c
Fri Dec 18 11:22:55 EDT 1998
>> "tonumber" goes crazy with negative numbers in other bases (not 10),
because "strtol" returns long, not unsigned long.
(by Visual C++)

** lstrlib.c
Mon Jan  4 10:41:40 EDT 1999
>> "format" does not check size of format item (such as "%00000...00000d").

** lapi.c
Wed Feb  3 14:40:21 EDT 1999
>> getlocal cannot return the local itself, since lua_isstring and
lua_isnumber can modify it.

** lstrlib.c
Thu Feb  4 17:08:50 EDT 1999
>> format "%s" may break limit of "sprintf" on some machines.
(by Marcelo Sales)

can be reallocated.
(by tomas; since 3.2 beta)

** lparser.c

Wed Aug 18 11:28:38 EST 1999
>> random(0) and random(x,0) are wrong (0 is read as no argument!).

** lparser.c
Thu Sep  2 10:07:20 EST 1999
>> in the (old) expression << ls->fs->f->consts[checkname(ls)] >>, checkname
