Summary: Assertion fails when boost thread terminates on Linux

Initial Comment:
When a boost thread uses a logger, and then terminates (under normal conditions), an assertion fails. This problem does not happen on Windows 7, only on my Raspberry Pi.

Using:
- log4cplus 1.1.0-rc8
- CMake build type debug with CMAKE_CXX_FLAGS="-std=c++0x"
- OS: Raspbian (derived from Debian ARM)

Client application using:
- shared library
- without wchar_t
- Boost 1.49

Error message:
cachip: /home/pi/prog/log4cplus-1.1.0-rc8/src/global-init.cxx:296: void log4cplus::ptd_cleanup_func(void*): Assertion `arg == reinterpret_cast<void *>(1) || arg == internal::get_ptd ()' failed.

This looks similar to the bug reported here:

I will apply the following change (later today, also attached). Please test
if it fixes your crash.

Thank you for the bug report. Is it easily reproducible? I have had
something similar reported before this one but I were not able to reproduce
it myself.
