Of course all software has bugs, but Lua is remarkably stable. All
variables in Lua are initialized to nil (on the Lua level); we often
test Lua with memory-tracking tools like Valgrind (on the C level). Are
you sure the bug is not a "regular" bug in your program? Does not your
program access external stuff that may change from run to run (and thus
cause the irreproducible behavior)?

What platform are you using? Did you compile Lua yourself? How? Do you
use C code?
