TOT failing with: undefined error code for 'unexpected non-zero initial branch'

Running the following on TOT fails with (this runs fine on lcov2.0.1)

lcov --capture --no-external --directory ~/gcda_gcno_data --base-directory ~/src --output-file /tmp/tmp2ec7df9c --branch-coverage --ignore-errors inconsistent --ignore-errors branch --ignore-errors unused

Bummer - this is a typo near line lcovutil.pm:4028: 'lcuvutil::..' -> 'lcovutil::...' (an 'o' not a 'u').
Fixed in my sandbox.

I suspect that I didn't notice it up to now because we don't use gcc/7 - and there is something funny in its output data.
(lcov should handle it - but may not right now).
I will push this fix with a couple of others after some testing.

I think that this one is fixed - but there may be another error that happens right after.
Could you give TOT another try, and report back? (Close if it seems fixed.)

Tested with TOT, I didn't hit the issue
