HYPRE_IJMatrixSetConstanValues failing on non optimized compilation

[GabrielNSD]

Hi there!

I am trying to run a Fortran code that uses Hypre. The code runs flawlessly when the optimization flag -O3 is used to compile it, but without it or using the other flags (-O1 and -O2) the program always fail in runtime.
Debugging it with gdb, an Segmentation fault error is indicated in hypre_ijmatrixsetconstantvalues_().

I have tried both hypre 2.30 and hypre 2.32 (with openMP) and the error persists. I am currently using gfortran 12.3.0

Best regards!

@GabrielNSD is the Fortran code open source? Can you provide instructions on how to reproduce your issue? Thank you!

@victorapm unfortunately the code is not open source, I am working in a minimum reproducible example that I can share. I am going to post it here as soon as it is finished
