Yes - I'm trying to compile using gcc instead of Intel. Spack is a package manager.

An array contains a value (1.8e+215) causing an assert to fail. I provided gdb output. Perhaps also useful - this same thing occurs on two different machines: $ lsb_release -a Description: Ubuntu 22.04.2 LTS $ uname -a Linux t480 5.15.0-72-generic #79-Ubuntu SMP Wed Apr 19 08:22:18 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux $ gcc --version gcc (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0 And $ lsb_release -a Description: SUSE Linux Enterprise Server 12 SP5 Release: 12.5 $ uname -a Linux discover12 4.12.14-122.156-default #1 SMP Wed Apr 5 06:49:18 UTC 2023 (026e398) x86_64 x86_64 x86_64 GNU/Linux $ gcc --version gcc (GCC) 12.1.0 -k.
