I see the sprintf call is still in the stacktrace, which is confusing because there should be no sprintf call in "lcc_num", the edited routine from decode_g2gnum.c Also the content of make.out are simply "make: Nothing to be done for `all'." It doesn't look like the rebuild worked. If you would like to access your machine to address the problem, please email me directly at address@hidden with the required login information. It's best not to reply back to the support-gempak account with that info. Michael > Michael, > OK I tried again and this time dcgrib2's binary is dated today. It's still > crashing.
