You will see from the above that the reporter himself has done this already.
Just for the record, the backtrace from the error is:
Program aborted. Backtrace:

gfc_vector.F90:807 contains a call that looks horribly like the problem line in
PR81758
call
this%container%vec_tile(q(4))%tile_batch(q(3))%batch_seg(q(2))%seg_elem(q(1))%&
&vector_elem_ctor(elem_val,ierr,assoc_only=assoc)
However, it is definitely the allocate that is the problem as evidenced by it
disappearing if STAT is not used.
Unfortunately, as Dmitry reports above, the fault also goes away in gdb :-(
