Like I said in an earlier e-mail, the code is isolated. However, to make things sure I added it as: #define BOOST_REGEX_DYN_LINK in the source code and there is no change. Then I defined it in Properties->Preprocessor Definitions. Then it complains as: "Mixing a Boost dll with a static runtime is a really bad idea ...". I don't know why?
That's hint as to where the problem may be: it is in general a really bad idea to use the static C++ runtime library in a dll (unless you're *very* careful about what interfaces are exposed), and you cannot use regex as a dll with a static C++ runtime. The problem is that your application gets two different runtime libraries, which can lead to all kinds of hard to trace memory errors: this is a Win32 not a Boost issue.
Other than that it's hard to say what the issue might be without seeing your code.
The surprising thing is that a single line of BOOST code (just an expression) disturbs the program. For example, I added: boost::regex sre("!NULL|sil|SIL"); only and didn't do anything with it. Then when I run the program with the perfectly working code (non-boost), it misbehaves. So I don't think it is a problem with my regex code as all.
That sounds like a possible runtime-library problem. Can you switch both your application and the dll to use the dynamic C++ runtime? John.
