Embedded Linux seg fault on blendcolor

  • Hello,

    I am using Qt 4.6.3. My target is an Atmel AT91SAM9263. Occasionally, and seemingly random, I get a seg fault with the following backtrace:

    #0 0x0019e428 in void blendColor<qrgb555>(int, QT_FT_Span_ const*, void*) ()
    #1 0x00167dd8 in qt_span_fill_clipped(int, QT_FT_Span_ const*, void*) ()
    #2 0x00169f1c in fillRect_normalized(QRect const&, QSpanData*, QRasterPaintEnginePrivate*) ()

    Going to v4.7.4 did not help. My app is not doing any special graphics, just progress bars, tablewidgets, listwidgets, etc. I do not have much low-level graphics experience, so I am not sure where to go from here.

    Any suggestions are appreciated. Thanks!
