Summary:                    stack smash with (assumed) case-sensitive file names
Description: 
FindFLEX.cmake was not available in cmake-2.6 but was added in cmake.2.8.

In order to allow find_package() for either version, I created FindFlex.cmake
(note the lowercase part of FLEX) in my CMAKE_MODULE_PATH. This file contains:

if (${CMAKE_VERSION} VERSION_LESS 2.8)
  set (FLEX_FOUND "false")
else ()
  find_package (FLEX)
endif ()

This works for Linux, but on windows, cmake dies with ERRORLEVEL=-1073741819,
i.e. 0xC0000005 which indicates a crash. Taking into account that the file
system is not case sensitive, I assume that find_package(Flex) and
find_package(FLEX) are not distinguished and thus result in a infinite loop of
above script.

The problem was seen with cmake 2.8.2.
