FWIW this has been failing all along (last report dates back Feb 17th),
now because of this:
lcov: ERROR: (negative) Unexpected negative hit count '-9' for line /home/coverage/pgsrc/pgsql/src/port/snprintf.c:529" while capturing from ./src/port/snprintf_shlib.gcda.
(use "lcov --ignore-errors negative ..." to bypass this error)
I added this flag as well, and the report is now running; we should have
results soon.
I hope the lcov people find time to fix all these problems :-(
