#2136 SciTE 4.2.1 / Mac OS crash on assert when inserting C preprocessor directive

[Isiledhel]

Assertion failed: (sc.state == (SCE_C_PREPROCESSOR|inactiveFlag)), function Lex, file /Users/neil/merc/scintilla/lexers/LexCPP.cxx, line 1311.

How to trigger:

1. Open empty file (make sure C/C++ language is active).
2. type : #else
3. assert is caught before hitting return

I also experienced same assert trigger with these sequences (but I cannot reproduce when filling this report so some steps must be missing)

1. working on a C file
2. type : #endif (no matching #if or #else)

3. assert is caught upon hitting return

4. working on a C file

5. position at the begining of a comment line ( // something )
6. hit return to insert a new line
7. assert is caught upon hitting #

[Neil Hodgson]

The asserts should not have been enabled for releases and that will be fixed in the next release.

These are situations that are invalid by the C language rules, #else must follow a #if, so the correct behaviour (whether to show the following code as active) is uncertain.
