      Qt 4.8.0
      qtCreator 2.4.1
      mingw 4.6.1 (From www.mingw.org)
      mingw 4.4.0 (Shipped with QT 2010.05)


      I have compiled qt 4.8.0 and qtCreator 2.4.1 from source using mingw on several PCs.

      For the lastest mingw 4.6.1(32bit, downloaded using "mingw-get-inst-20111118" tool from www.mingw.org), Win7 sp1 ×64, WinXP pro sp3 ×86 and Win2003 sp2 ×86 were used as the OS to compile the source of qt 4.8.0 and qtCreator 2.4.1.

      After sucessful compilation in three platforms (with deal with few errors), there are some problems when runing.

      1. designer crashes on both WinXP and Win2003, while works fine under win7 ×64. ( the error dialog seems show the access violation with msvcrt.dll (version 7.0.2600.5512 on WinXP) )

      2. qtCreator works fine, except crashes when click on "options"->"disigner" tab under WinXP and Win2003.

      3. gdb shipped with mingw 4.6.1 can not work properly, in all cases breakpoint were ignored. as table 1 shows.

      For mingw 4.4.0 bundled in old Qt IDE (2010.05) , all works fine, except the gdb, shown in Table 2.

      here are gdb version info, bundled with mingw 4.4.0 from old Qt IDE (2010.05)
