It doesn't seem to work as intended, but I've had no time to
debug it yet.  Here's output from one build failure where
I tried to continue with "exit 1".  As you can see, the build
stopped a few more times where I also used "exit 1".  At one
point I decided to give up with "exit 3" which caused a few
strange errors and then the build continued to the end!?

Maybe you can make sense of it.

Here are the two errors from the longer log below:

  scripts/functions: line 401: stop-: syntax error: operand expected (error token is "-")

    399 CT_EndStep() {
    400     local stop=$(CT_DoDate +%s%N)
    401     local duration=$(printf "%032d" $((stop-${CT_STEP_START[${CT_STEP_COUNT}]})) |sed -r -e 's/([[:digit:]]{2})[[:digit:]]{7}$/\.\1/; s/^0+//; s/^\./0\./;')

  scripts/functions: line 199: [: -le: unary operator expected
    168 CT_DoLog() {
    ...
    199               if [ ${cur_l} -le ${max_level} ]; then

Even though it's not fully working yet the debug shell is
still very useful for me.  Saved me a lot of time. :-)


Thanks
Johannes


(note the build was running on some ancient RedHat machine
so the actual build error is not so interesting for you)
