[help] Run gemma example using the command line on my mac, got some runtime errors.

When I run gemma example using the command line on my mac, I get the following error. It looks like this is a compilation error with some package.

runtime errors:

No real clue what is going on but I doubt this issue is related to candle. From the error messages I think the important bit is that the processes ended up receiving a sigkill from the os. Googling this, I came across this issue and others in the rust compiler repo so maybe you want to dig more into these threads.
(and if you ended up finding a workaround / explanation, certainly come back to this issue so as to make it easier for the next people that might run into it)

I checked several similar issues, and I think it is caused by the incompatibility between the rust compiler version and the dependent libraries (on the x86_64-apple-darwin platform). Here is my rust version and other configuration.

(base) bofeng@ip-192-168-0-104 ~ % rustc -vV
rustc 1.77.0 (aedd173a2 2024-03-17)
binary: rustc
commit-hash: aedd173a2c086e558c2b66d3743b344f977621a7
commit-date: 2024-03-17
host: x86_64-apple-darwin
release: 1.77.0
LLVM version: 17.0.6

The amazing thing is that when I build the debug version, it compiles successfully.
