Comment (by foretspaisibles):

 When trying to run the command on the terminal, it does not display any
 logs besides the SBCL banner, as can be inferred from the logs.
 Interrupting the program with ^C does not yield, which is usually the sign
 that the process is in a non interruptible system call. Rerunning again
 under dtruss shows the trail:

 {{{

 mmap(0x0, 0x80A004, 0x7, 0x41002, 0xFFFFFFFFFFFFFFFF, 0x0)               =
 0x5800000 0
 mmap(0x0, 0x80, 0x7, 0x41002, 0xFFFFFFFFFFFFFFFF, 0x0)           =
 0x1F2000 0
 }}}
