Summary: Scintilla assertion fails on long PHP heredoc quotes
Initial Comment:
When dealing with a long heredoc style PHP string, the scintilla component will
sometimes fail the assertion:
PLATFORM_ASSERT(lengthStyle == 0 ||
(lengthStyle > 0 && lengthStyle + position <= style.Length()));
CellBuffer::SetStyleFor(int position, int lengthStyle, char styleValue, char
mask) in CellBuffer.cxx. I'm not sure of the exact conditions that makes it
crash, but depending on the contents, it will sometimes crash when trying to
type into the file, and sometimes won't even let you scroll far enough to see
it before crashing. However, per file it seems to be pretty consistent. So,
for example, if one file has a typing crash, it will always crash when trying
to type into that same location.
This was tested both with Notepad2 (which is where I got the actual assertion
line from) and SciTE (which tends to hang instead of crash, but still with the
same consistency), so it seems quite likely to be the Scintilla component
itself. Also, just pasting text doesn't trigger the crash, so to test it,
you'll need to not only paste a bunch of random text, but then also try to type
normally after it all. Also, this doesn't happen with normal single- or
double-quoted strings, just heredoc strings.
