# lua -l re
lua: /usr/share/lua/5.1/re.lua:105: loop body may accept
empty string
stack traceback:

where line 105 is:
local S = (m.S(" \f\n\r\t\v") + "--" * (any -
Predef.nl)^0)^0
Also, LPeg’s own test set crashes between asserts:
# lua l/lpeg-test.lua
General tests for LPeg library
version 0.10
lua: l/lpeg-test.lua:123: bad argument #2 to '?' (number
expected, got userdata)
stack traceback:

where line 123 is:
word = alpha^1 * (1 - alpha)^0
I am pretty sure that the problem is not within Lua or LPeg
per se,
since we have gotten Lua working on ARM architecture
(PandaBoard)
earlier. Also, other Lua libraries seem to work (e.g.,
LuaSocket).
Unfortunately, our current target has very limited
debugging support, so the hunting for the root cause is
quite slow.
Has anybody encountered similar problems or has any
helpful hints?
Thanks and take care.
