Segmentation fault (core dumped) with a minimal example #6
Description
On commit 91c97f0 (latest), I created examples/benchmarks/playground.py with the following content:
import hecate as hc
import sys
import numpy as np
@hc.func("c")
def playground (cin) :
return cin*cin
modName = hc.save("traced", "traced")
print (modName)Steps to reproduce:
source .venv/bin/activate
source config.sh
hc-trace playground
hbt dacapo 40 playground SEAL CPUThe execution results in a segmentation fault:
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
