[Ecls-list] Debuggability of CMP.

Good day Juan,
While attempting to tame some MOP issues I have tried to make
the compiler behave more friendly.
Namely, at this moment, AIUI, the file compiler doesn't enter the debugger
whenever any SERIOUS-CONDITIONs arise, and rather just exits abruptly.
Realising this, I have tried to (handler-case (compile-file "buggy.lisp")
but the backtrace didn't have anything beyond si:bytecodes.
So, I thought, I'd rebuild ECL with nice proclamations here and there.
So, first I tweaked bare.lsp.in and compile.lsp.in to substitute
(optimize (debug 3) (safety 3) (speed 0) (space 0)) in all proclamations
which were already present.
This results in ecl_min.exe stuck during lisp boot, in fill_vector,
for what looked like forever.
I have tried to reduce the safety and increase speed, with no change.
Then I reverted all proclamations to their original values and only have
set the per-module compilation proclaim in bare.lsp.in to highest debug
That worked, but didn't have any effect on the amount of backtrace
Besides -- the last proclaim form in compile.lsp.in doesn't seem
to be able to have effect -- it is overridden by the proclamation
regards, Samium Gromoff
