Hi Alex, Thanks for your reply. To Igor: The exception type is 'Access Violation' raised in boost::ends_with function. Regards, Ivan 2012/10/31 Alex Perry <Alex.Perry@smartlogic.com>

Sorry forgot to add you to cc - it speeds up conversation if you are in digest mode for boost list!

People said it's very unlikely to be compiler's bug, but when compiled in debug moded(or disable optimization), the problem does disappear. I have been stuck with this problem for quite a few hours. Any help is appreciated. Thanks in advance. ...snip...

Not sure if its any help but just tried compiling this with VS2010 and VS2012

From VS command prompt (with boost version 1.51 pathed into include and lib)

cl test.cpp /EHsc /O2

and resulting test.exe is fine (with or without /O2)

So does look like a problem with vs2008 specifically (sorry don't have one available to try any longer)
