The program builds succesfully but after a few seconds i get this unhandled exception which stops the debugging.
This exception is located in imgui_draw.cpp, at the line 3277. This is the part of the code:

// Setup fallback character

const ImWchar fallback_chars[] = { (ImWchar)IM_UNICODE_CODEPOINT_INVALID, (ImWchar)'?', (ImWchar)' ' };
FallbackGlyph = FindGlyphNoFallback(FallbackChar);
if (FallbackGlyph == NULL)
{
    FallbackChar = FindFirstExistingGlyph(this, fallback_chars, IM_ARRAYSIZE(fallback_chars));
    FallbackGlyph = FindGlyphNoFallback(FallbackChar);
    if (FallbackGlyph == NULL)
    {
        FallbackGlyph = &Glyphs.back();
        FallbackChar = (ImWchar)FallbackGlyph->Codepoint;
    }
}

FallbackAdvanceX = FallbackGlyph->AdvanceX;
for (int i = 0; i < max_codepoint + 1; i++)
    if (IndexAdvanceX[i] < 0.0f)
        IndexAdvanceX[i] = FallbackAdvanceX;

}
