I run into a build error when building KLayout 0.25.3 against GCC libs 8.1.0:

from ../../../src/db/db/dbCellMapping.cc:24:
[...]
/usr/include/c++/8.1.0/bits/stl_iterator_base_funcs.h:183:2: error: no match for 'operator--' (operand type is 'db::SortedCellIndexIterator')

I have a patch (see attached) that gets around the issue by defining the missing operator.

I can confirm both the build failure and the fix.

Note that the error is that this class has "typedef std::random_access_iterator_tag iterator_category" but does not meet the requirements of a random-access iterator. The GCC 8.1.0 implementation of std::lower_bound uses the decrement operator.

Another confirmation here. I've added the patch to the Gentoo build.
