-- Information about the crash:
I tried to enter "Configure KDevelop" using Ctrl+Shift+, 
Also tried via the menu "Settings->Configure KDevelop"

I hit the following assert:

kdevelop: /home/peje/kdesrc/kdevelop/plugins/astyle/3rdparty/libastyle/ASFormatter.cpp:3841: std::__cxx11::string astyle::ASFormatter::peekNextText(const string&, bool, std::shared_ptr<astyle::ASPeekStream>) const: Assertion `sourceIterator->getPeekStart() == 0 || streamArg != nullptr' failed.


Compiled kdevelop master via kdesrc-build

The crash can be reproduced every time.

make AStyleStringIterator::getPeekStart() return valid values

The astyle v3 API introduced a new virtual ASSourceIterator::getPeekStart()
method that has to be implemented in classes inheriting ASourceIterator.
Currently that method is only used in an assert that verifies whether it
returns a valid (i.e. positive) value. This was overlooked in the upgrade
of the bundled astyle library code.
