ASDF had some annoyances related to compiler warnings, but waht I experience is a 
different issue.I think so because I use my code to compile and load lot of libraries.
Maybe on them produce compiler warnings or fail to compile at all, and my code
always catches the error (even on ECL and other lisps).

But sometimes ECL starts to enter debugger. 

What is important, it happens not always when this file is compiled, but seems
to depend on what compiler did before compiling this file. I have impression 
something in ECL sets compiler:*compiler-break-enable* to T, which 
causes entering debugger.

See attach for a lisp session (copy paste from console).

When in debugger i chose the "try recompiling" restart, and every time 
the file is recompiled I again trap into the debugger.

Until I set compiler:*compiler-break-enable* to NIL, 

After this compilation still fails, but the debugger is not entered, and my code 
continues as expected (i.e. handler-case catches the error)

Best regards,
