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.

1) Do you have some more info on the error? Anything else given?<br>
My first guess: did you set<br>
PARAMETER(PTRACERS_num = 9 )<br>
in PTRACERS_SIZE.h?<br>
<br>
2) You have to give the exf parameters in data.bling, not data.ext. <br>

When I try to add silica as 9th tracer (#define USE_SIBLING in BLING_OPTIONS.h), the model crashes in the beginning giving the following error message "Program received signal SIGSEGV: Segmentation fault - invalid memory reference.".<br>
