<br>
I have a code which uses PETSc and it was working fine. However, I <br>
haven't used the code for a while and now we've migrated to a new cray <br>
cluster so the compilers have been updated. I'm using gnu fortran.<br>
<br>
When running the code now, I got the error:<br>
<br>
Error termination. Backtrace:<br>
At line 294 of file <br>
/home/users/nus/tsltaywb/myprojects/ibm2d_high_Re_staggered_coef/PETSc_solvers.F90<br>
Fortran runtime error: Index '-17591876251192' of dimension 1 of array <br>
'ppv' below lower bound of 1<br>
<br>
I have attached my makefile. Wonder what I should change to prevent the <br>
above error.<br></blockquote><div><br></div><div>This looks like an integer overflow error.

Thank you very much.<br>
