[Boost-users] Boost::regex causes runtime errors with CLR

Hi,

I'm trying to use boost::regex with a "Windows Forms Application" in 
Visual Studio 2005. Everything works fine with normal C++, and even 
using a "CLR Console Application." But when I use the "Windows Form 
Application" template the program crashes while initializing variables. 
Basically I take code like:

#include <boost/regex.hpp>
using boost::regex;
using boost::regex_search;
bool h() {
    return regex_search("asdfasdf",regex("sd"));
}

put it in a separate file, turn off precompiled headers for that file, 
and never actually call h(). The program crashes instantly with a debug 
assertion failed at dbgheap.c/Line 1414/_CrtIsValidHeapPointer. The call 
stack looks like:
...
     msvcr80d.dll!__dllonexit(int (void)* func=0x00446110, void (void)* 
* * pbegin=0x0012eab8, void (void)* * * pend=0x0012eab0)  Line 273 + 
0x11 bytes    C
 temp.exe!_onexit(int (void)* func=0x00446110)  Line 110 + 0x11 bytes    C
 temp.exe!atexit(void (void)* func=0x00446110)  Line 127 + 0x9 bytes    C
 temp.exe!boost::re_detail::`dynamic initializer for 'block_cache''()  
Line 189 + 0x2b bytes    C++
...

It does this whether I compile the file with regex with the /clr flag or 
not (although the /clr flag gives a lot of errors, one of which isn't 
about converting fastcall to stdcall:
include\boost/shared_ptr.hpp(92) : warning C4793: 'vararg' : causes 
native code generation for function 'void 
boost::detail::sp_enable_shared_from_this(const 
boost::detail::shared_count &,...)'

Thanks,
