It has probably to do with sjlj exceptions in g++. Personnaly I build
my own mingw cross compiler (linux->windows) with the following
option: --disable-sjlj-exceptions. Otherwise, I can get that sort of
issues.
But then, I build boost with the cross compiler on linux. The toolset
is gcc, not mingw. I can still use the libraries on windows with
CodeBlocks.

My command line for b2 is:
./b2 --layout=system --user-config=user-config.jam link=static
theading=multi runtime-link=shared target-os=windows threadapi=win32
variant=release install
with user-config.jam containing:
using gcc : : i686-pc-mingw32-g++ : <compileflags>-DBOOST_THREAD_USE_LIB ;

Hope this can help you.

Cheers,

Frédéric
