# The purpose for this fix is to change:
# FD_ToolTip *fdui = (FD_ToolTip *) fl_calloc(1, sizeof(*fdui));
#
# to
#
# FD_ToolTip *fdui = (FD_ToolTip *) fl_calloc(1, sizeof(FD_ToolTip));
#
# This is because *fdui before fdui is initialized is a dangerous operation.
# The fixed version is the equivalent but safer.
