FTBFS = "Fails To Build From Source"

guix package --no-substitutes -i openblas

resulted in the error below on Guix System running on a KVM in Proxmox
VE using the default CPU called "kvm64".

---
OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 ./sblat3 < ./sblat3.dat

Program received signal SIGILL: Illegal instruction.

Backtrace for this error:
#0 0x7ffff7d2fc1a

bash: line 1: 25848 Illegal instruction OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 ./sblat3 < ./sblat3.dat

make[1]: *** [Makefile:167: level3] Error 132

I shutdown the VM and changed the CPU type to "host" (which provides the full
instruction set of my CPU to the VM) and was able to build successfully
using the same command.

openblas 0.3.20 out /gnu/store/xghpgl3fnr603z16vg7hldmpxygriqm2-openblas-0.3.20

Thanks for the report. That's probably due to some limitation in QEMU.
It'd be best to report it there -- it's outside of the scope of Guix,
although you could offer a Guix-based reproducer in your upstream
report.

Closing.
