The problem is solved. I was inserting the dart handles to the 3-cells to be
removed from LCC inside a std::vector and then removing them(calling
remove_cell) in another loop, as you suggested, but I forgot to clear the
vector after each loop. Once I added /vector.clear()/ before every call to
populate the vector, code assertion violation error disappeared. Following
is the pseudocode,

*Erroneous code:*

for (iterate N times)
{
    for (iterate over linear cell complex, lcc)
      if (some condition)
        vector.push_back(dart_handle_of_cells_to_be_removed);
    
    for (iterate over vector using iterator /iter/)
      remove_cell<LCC, 3>(lcc, */iter/);
}

*Fixed code:*

for (iterate N times)
{
   / vector.clear();/ <----- removes references to already deleted cells
from previous iteration
    for (iterate over linear cell complex, lcc)
      if (some condition)
        vector.push_back(dart_handle_of_cells_to_be_removed);
    
    for (iterate over vector using iterator /iter/)
      remove_cell<LCC, 3>(lcc, */iter/);
}
