Thanks for the report. Can you help debugging it?
  - Does   1.0 / -0.0 < 0   evaluate to true or false?
  - Does   1.0L / -0.0L < 0  evaluate to true or false?
  - At test-vasprintf-posix.c:1309, what is the resulting string?
  - When you single-step from test-vasprintf-posix.c:1304 or :1305 on,
    where is the '-' sign dropped?
