While checking strace(1) and ltrace(1) output, I've found that
the correct behavior coincides with a single DNS request, while
the buggy one coincides with three.
Thus, I've breakpointed GDB at recvfrom () and got the
backtraces MIME'd. As far as I can see, the URL is correctly
passed down to the ocfetchurl () NetCDF internal function.
Unfortunately, even though libcurl3-dbg is installed, the
arguments to the Curl_* functions aren't shown.
Any hints?
$ dpkg -l \*-dbg | grep -E ^i
ii libcurl3-dbg 7.21.0-1 libcurl compiled with debug symbols
ii netcdf-dbg 1:4.1.1-5 debugging symbols for NetCDF
