Latest 3.3 - Exception when model has no rows

5 years 8 months ago #1 by Pascal
Hi,

Updated to the latest 3.3 and within the first minute of testing got application crashing. It consistently crashes whenever a valid model has no rows (rowcount is 0).

Below is the exception:
eax=0012306c ebx=00000000 ecx=04649e50 edx=04649e50 esi=00000005 edi=0021ce38
 eip=57c60156 esp=00122ffc ebp=00123004 iopl=0         nv up ei pl nz ac pe nc
 cs=001b  ss=0023  ds=0023  es=0023  fs=003b  gs=0000             efl=00010216
 >   56:     inline bool ref() Q_DECL_NOTHROW {
 qtngridd3!QtPrivate::RefCount::ref+0x6:

Exception at line 2735 of file qtngridtableview.cpp
GridTableColumn* GridTableView::getNextColumn(const GridTableColumn* anchor) const
{
    QListIterator<GridColumnBase *> iterator(m_columnVisualIndexies);
