OK. Comming up with a fix was quite easy, specially given that, a I said, this was a known problem and I had the fix waiting to be applied (but needed a linux box to test it). I still don't understand why it showed up after my lastest changes Anyway, here's the diff: 79,91d78 < // Daniel Wallin discovered that bind/apply.hpp badly interacts with the apply<> < // member template of a factory as used in the optional<> implementation. < // He proposed this simple fix which is to move the call to apply<> outside < // namespace boost. < namespace boost_optional_detail < { < template <class T, class Factory> < void construct(Factory const& factory, void* address) < { < factory.BOOST_NESTED_TEMPLATE apply<T>(address); < } < } < 325c312 < boost_optional_detail::construct<value_type>(factory, m_storage.address()); ---

Unfortunately, I couldn't test it on gcc. I got stuck pretty much all morning on this error: gcc.link ../../../bin.v2/libs/optional/test/optional_test.test/gcc-4.0.2 Copyright/debug/optional_test /usr/lib/libc_nonshared.a(elf-init.oS)(.text.__i686.get_pc_thunk.bx+0x0): In function `__i686.get_pc_thunk.bx': : multiple definition of `__i686.get_pc_thunk.bx' ../../../bin.v2/libs/optional/test/optional_test.test/gcc-4.0.2 Copyright/debug/optional_test.o(.gnu.linkonce.t.__i686.get_pc_thunk.bx+0x0):/usr/include/c++/3.3/new:94: first defined here collect2: ld returned 1 exit status "g++" -o "../../../bin.v2/libs/optional/test/optional_test.test/gcc-4.0.2 Copyright/debug/optional_test" -Wl,--start-group "../../../bin.v2/libs/optional/test/optional_test.test/gcc-4.0.2 Copyright/debug/optional_test.o" -Wl,--end-group -g ...failed gcc.link ../../../bin.v2/libs/optional/test/optional_test.test/gcc-4.0.2 Googling indicates that I have my gcc installation messed up, but couldn't fix it yet. So, can anyone tried the patch on gcc? It works here on VC80 and VC7.1. Best Fernando Cacciola
