I think also that it would be really important that also this versions are build. so everyone can use what he wants . Otherwhise it is really hard to find errors like this ones... Best regards Hansjörg Jean-Francois Bastien schrieb:
The _SECURE_SCL macro in Visual Studio's (Dinkumware's) STL changes the ABI for standard types, which causes silent ODR violations when Boost static libraries and the main program linking with them don't define this macro the same way. This problem manifests itself as runtime crashes.
There's been discussion before (see links at the end) to solve this by using different library names in the build system to distinguish different ABIs. The discussions brought up issues: - _SECURE_SCL implies a performance cost. - _SECURE_SCL might not be conformant with the complexity requirements (no clear conclusion was reached on this). - Should the compiler's default behaviour be Boost's default (i.e. _SECURE_SCL isn't defined)? - The Windows version of the Intel compiler has a bug around partial function template ordering which can be solved by defining _SECURE_SCL to 0.
There's already a Trac issue for this: http://svn.boost.org/trac/boost/ticket/2086
Could we reach a consensus on adding this to the library name mangling?
Is it too late for 1.37.0?
Thanks,
JF
