[Lazarus] Compilation aAn unhandled exception

[Ernest V Miller]

Hi list!

I am working on lazarus desktop gui application. Every 2 or 3 hours of
active development after regular writing code and fixing compilation errors
I suddenly get

      main.pas(1,1) Fatal: Compilation aAn unhandled exception occurred at
$000000010006B1DC :

instead of normal success or error messages. After that I simply say
"compile" again and then the compilation process restarts and finishes
successfully.

Does anybody know what this problem may be and what info should I provide
you to get down to this exception?

I use laz 1.0.6 and fpc 2.6.0 x64
