Unhandled exception: page fault on read access to 0x00000000 in 32-bit code
(0x004119e7).

The function
msvcp60.??A?$basic_string at DU?$char_traits at D@std@@V?$allocator at D@2@@std@@QAEAADI at Z
is the string-operator at.
If you track that function, one call is with an empty string (this->size == 0
and more important this->ptr == NULL) at position 0. The return value is then
this->ptr+pos == NULL, which then causes the page fault.
Such a call shouldn't happen, or does it work to access an empty string at
position 0 under Windows.
