and I'd like to correct myself: under rosetta it failed with wrong libboot.so architecture.

Here two patches:
 - flush stdout to make this error visible
 - fix this error by respect CFLAGS to build libboot.so

Now it failed the same way on both machines with stacktrace:

Thread 0 Crashed::  Dispatch queue: com.apple.main-thread
0   raw_pre_gcl                   	       0x1000acd81 siLheap_report + 177
1   raw_pre_gcl                   	       0x10005c0ca fSeval_src + 410
