User sees crash in CudaText, when he makes paste from clipboard. He tells how to repeat crash: https://github.com/Alexey-T/CudaText/issues/1146

First i saw error in debugger in lazutf8 (UTF8CharacterLength(..)), after Lazarus update I don't see source of crash now (only some asm dump).

User uses Win32, I use Linux gtk2 x64. FPC 3.0.0 (win) and 3.0.2 (linux).

You don't see the source code for function UTF8CharacterLength() any more? How come?

You don't see the source code for function UTF8CharacterLength()

I don't see which place gives AV (on pasting text), is it in this^^^
func, or not. I only see last stop at ...:=UTF8CharacterLength(). Then i
removed this call and replaced it with ...:=Length(UTF8Decode(s)). now
this crash gone. but new code is slower.

My workaround don't help, still AV on pasting. Both cases give AV in fpc_ansistr_dec_ref. Here is asm window:

I found the reason, it's my bug with generic lists. Alexey

Ok. In future you can build the whole IDE with debug flags, for example with the "Debug IDE" profile in Configure Build Lazarus window.
Packages like LCL and LazUtils also get the same debug flags.
