#292 QP-C-C++ on 64 Bit Linux - Setting of Current-Obj - AO_Obj from QView raises segmentation fault

[Anonymous]

in qs_rx.c:735
typecast must be to uint64_t, not uint32_t
case WAIT4_OBJ_ADDR: {
l_rx.var.obj.addr |= ((uint64_t)b << l_rx.var.obj.idx);

Correction: Not the setting of the AO_Obj raises the segment violation, but a subsequent posting of an event (qview - events - post).
