    Description

      When building QT 6.8.0-beta4 on an ARM system, qdrawhelper.cpp throws a warning on the following lines (warning C4700):

      1589 - uninitialized local variable 'v_top' used

      1590 - uninitialized local variable 'v_bot' used

      1809 - uninitialized local variable 'v_top' used

      1801 - uninitialized local variable 'v_bot' used

      These warnings end up turning into breakpoints in MSVC compiled applications when using certain GUI functions due to these uninitialized variables.
