Start seeing Unhandled signal SIGSEGV from our rust app when upgrading to version 0.1.48 from 0.1.47

Since we upgrade mimalloc crate from 0.1.47 to 0.1.48, we started seeing Unhandled signal SIGSEGV error from our error logs. From our stack trace related to these errors, we found the following:

#24 0x00007e3c6cbd7d13 in malloc_consolidate (av=0x7e3a6c000030) at ./malloc/malloc.c:4876

#32 0x00007e3c6cc57c6c in clone3 () at ../sysdeps/unix/sysv/linux/x86_64/clone3.S:78

For now, we have reverted back to use version 0.1.47. Hopefully, the future release will handle this error. Thanks
