[MITgcm-support] Error related to BLING

without looking at source code,
it seems that G_SI is missing in the BLING_BIO_NITROGEN call sequence, unless it is defined in an include file somewhere. Also check that G_SI is declared as an argument in the BLING_BIO_NITROGEN subroutine.

So the error may not be due to this. Also the same model setup is running fine for the MITgcm-checkpoint67j (2019/06/18 ) release. This is the version where the USE_SIBLING option is added to the BLING package for the first time. However, I want to use the latest (or recent year) release. As Matthew asked I am also including the detailed message I get on screen when the model crashes. My STDERR files don't contain any error messages. So is this problem related to MITgcm release ?
