Re: [Boost-users] boost::function and cross dll call issue

Sooo, I found the bogus. The host application had a struct member alignment set to 16 bytes which did a bad job for the boost header :) Sam -------- Original-Nachricht --------

Hello, I have a weird access violation when using boost::function which is

one DLL to another. At work we use an engine that loads libraries at runtime.

You MUST check following basic points:

1. Make sure that they use **exactly same** version of Boost with same flags (debug/release etc)

2. Do all the DLLs use exactly the same runtime, such that something allocated    in one DLL and deallocated in other calls exactly the same functions.

   Best try to check it with depends.exe program and check if the use    and load same MSVCxxx.DLL

   Including same debug/release and exact version.

2. Make sure that they both use Dynamic Runtime linking (i.e. do not link    with MSVC runtime statically)

Just hints to debug
