boost::filesystem::path::generic crashes on Windows while attempting to build a network share path

[alexandra.ghecenco@…]

I'm attempting to check whether a file on a shared path exists. The path is an unaccessible RDC share on WinXP.

Code snippet:

bool fileOk = boost::filesystem::exists(i_pFileName, ec) && boost::filesystem::is_regular_file(i_pFileName, ec);

pFileName is a const char*, value

\\tsclient\E\floating_Jasper.cap

That specific path is inaccessible.

I can't post the whole call stack because of company policy, but the faulting boost frames are as follows:

I'd expect this to return an error code and not crash.
