当前不会命中断点。没有调试器目标代码类型的可执行代码

Question

简介：代码在发布模式下不起作用。在调试中工作。

这显示在我的断点之一上：

代码点是：

void Font::operator<<(std::string s)
{
    this->printf(s); // this line
}

这个方法是这样调用的：

float oneframe;
oneframe = (double)elapsed/ 1000000.0;

float ffps =1. / oneframe;
int fps = ffps;
char txt[200];
sprintf(txt, "%d FPS", fps);
font << txt; // displays text

Printf 是：

void Font::printf(std::string s)
{
    UINT lines = 0;
    std::vector<float> offsetX;
    float offsetY=0;
    UINT length = s.size();
    XMMATRIX M = XMMatrixScaling(m_scaling.x, m_scaling.y, m_scaling.z)*
        XMMatrixTranslation(m_translation.x, m_translation.y, m_translation.z);
    float fontLength=0;
    float fontHeight = 60.0f / windowHeight;
    float fontWidth = 60.0f / windowWidth * 0.6f;

    m_deviceContext->VSSetShader(m_vertexShader, 0, 0);
    m_deviceContext->IASetInputLayout(m_inputLayout);
    m_deviceContext->PSSetShader(m_pixelShader, 0, 0);
    m_deviceContext->PSSetShaderResources(0, 1, &m_texture);
    m_deviceContext->PSSetSamplers(0, 1, &m_sampler);
    m_deviceContext->OMSetDepthStencilState(m_dsOff, 1);

    if (m_anchor != TOP_LEFT) 
    {
        float offset = 0;
        for (int i = 0; i < length; i++)
        {
            offset += m_kerning*widthMap[s[i]];
            if (s[i] == '\n' || s[i] == '\r' || i == length - 1)
            {
                offsetX.push_back(offset);
                offset = 0;
            }
        }
    }
    for (int i = 0; i < length; i++)
    {
        XMFLOAT3 TL(-1, 1, 0), BR(1, -1, 0);
        XMVECTOR vTL, vBR;
        if (s[i] == '\n' || s[i] == '\r')
        {
            fontLength = 0;
            lines++;
            continue;
        }
        switch (m_anchor)
        {
        default:
        case TOP_LEFT:
            vTL = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontLength, -m_leading*lines, 0)), M);
            vBR = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontWidth + fontLength, -m_leading*lines - fontHeight, 0)), M);
            break;
        case TOP_RIGHT:
            vTL = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontLength - offsetX[lines], -m_leading*lines, 0)), M);
            vBR = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontWidth + fontLength - offsetX[lines], -m_leading*lines - fontHeight, 0)), M);
            break;
        case BOTTOM_LEFT:
            offsetY = m_leading*offsetX.size();
            vTL = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontLength, -m_leading*lines+ offsetY, 0)), M);
            vBR = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontWidth + fontLength, -m_leading*lines - fontHeight+ offsetY, 0)), M);
            break;
        case BOTTOM_RIGHT:
            offsetY = m_leading*offsetX.size();
            vTL = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontLength - offsetX[lines], -m_leading*lines + offsetY, 0)), M);
            vBR = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontWidth + fontLength - offsetX[lines], -m_leading*lines - fontHeight + offsetY, 0)), M);
            break;
        case CENTER:
            {
                offsetY = m_leading*offsetX.size() / 2;
                float halfOffsetx = offsetX[lines] / 2;
                vTL = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontLength - halfOffsetx, -m_leading*lines + offsetY, 0)), M);
                vBR = XMVector3TransformCoord(XMLoadFloat3(&XMFLOAT3(fontWidth + fontLength - halfOffsetx, -m_leading*lines - fontHeight + offsetY, 0)), M);
                break; 
            }
        }
        XMStoreFloat3(&TL, vTL);
        XMStoreFloat3(&BR, vBR);
        assert(updateBuffer(TL, BR, fontMap[s[i]]));
        UINT stride, offset;
        stride = sizeof(SimpleVertex);
        offset = 0;
        m_deviceContext->IASetVertexBuffers(0, 1, &m_vertexBuffer, &stride, &offset);
        m_deviceContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST);
        m_deviceContext->Draw(6, 0);
        fontLength += m_kerning*widthMap[s[i]];
    }
    m_deviceContext->OMSetDepthStencilState(m_dsOn, 1);
}

这就是它变得奇怪的地方。我在发布模式下收到此通知。上面的代码在调试中完全有效。无论出于何种原因，当我切换到 Release 时它都不起作用。我检查了发送到函数的 txt 变量，它有文本。对我来说，似乎代码以某种方式被优化了。

我还删除了 Debug 和 Release 文件夹中的所有内容，并进行了全新的构建。没有什么。我已经从 VS 测试了没有运行的可执行文件，结果相同。 Release 中的调试显示 txt 中有文本，但我无法确定发生了什么，因为调试器似乎正好漂浮在 font << txt.

上方

Answer 1

我确实找到了答案。在 printf 的末尾附近使用了一个 assert。 Release 中没有断言运行。仅在调试中。
