    Description

      I get segmentation fault in QFontMetrics::width() function if:

      • fontconfig is used
      • bitmap font is used (eg. Adobe Helvetica) with small size (eg. 7 pixel)
      • GUI is not enabled in the application

      Please compile the attached small example. If size is set with setPixelSize(8), the function work properly, but it fails when 7 pixel is set.
