On some occasions, when running Editor in debug mode, I am being notified about assertions in Scintilla component.
This usually occurs when I open a script, select several lines, and hit Delete key.
For example:
Quote
Assertion [line < pdoc->LinesTotal()] failed at ..\scintilla\src\Editor.cxx 1932
Quote
Assertion [useCount == 0] failed at ..\scintilla\src\Editor.cxx 217
The raised assertion causes program to abort, which is pretty annoying; this does not happen in release version though.
Strange thing is that sometimes I can reproduce this over and over by quiting without save, reloading the project and repeating the action.
Then, at some point it stops reproducing...
Any thoughts anyone?
Never happened to me, and I always run in debug.
Does it throw an exception? Maybe you have an exception enabled which you can disable (in the exceptions window). That's all I got...
Still happening. On one occasion this happened when I was replacing (pasting over) all text in script by clipboard contents (so that it had to first delete all contents, I guess)
This is not an exception, but an internal Scintilla's "assertion".
The stack trace:

The assertion that fails in Editor::LayoutLine (Editor.cxx):
PLATFORM_ASSERT(line < pdoc->LinesTotal());
line = 1,
pdoc->LinesTotal() returns 1
I suspect there's a mistake in logic somewhere.
*Bump*
Bumping this just in case someone wants to take a look and find out how to fix this, because it annoys the hell out of me when I am debugging the Editor.
This happens all the time to me and bugs me a lot too. I didn't know it was caused by an assertion.
