Cargo Build bricks, "Error: future cannot be sent between threads safely", on two different baremetal Linux
Describe the bug A clear and concise description of what the bug is. On new installations in non-wsl environments, Ubuntu 22.04 and Arch Linux, cargo build breaks with 7 "error: future cannot be sent between threads safely" errors. This occurs on two different machines, and two different x86_64 operating systems.
Indicate any of these common scenarios that apply:
- [ ] a program hangs under hermit
- [X] hermit panics internally
- [ ] hermit runs the program but divergence (nondeterminism) occurs
To Reproduce Minimal input to reproduce the behavior. On baremetal x86_64 linux, git clone, update
Expected behavior A clear and concise description of what you expected to happen. Cargo build should pass all building/compiling checks and end.
Environment
- [X] Linux kernel version (
uname -a): 6.4.10-arch1-1 & Ubuntu 22.04 - [ ] CPU version (
/proce/cpuinfo): - [ ] Linux distro flavor (
/etc/issue,/etc/redhat-release):
Additional context
Attach the logs to this issue as a text file generated by hermit --log=trace --log-file=FOO run.
