Tried it on my 14-CURRENT system from Jan 21 and indeed it does reproduce,
until I enable debugging. Here's the back trace:

(lldb) bt                                          
* thread #1, name = 'qbs-1684', stop reason = signal SIGBUS

    frame #7: 0x00000000002024a0 qbs-1684`_start(ap=<unavailable>,
cleanup=<unavailable>) at crt1_c.c:73:7    

Now, having rebuilt devel/qt5-script with debugging, it no longer core dumps.
But if I use the existing core I see:

(lldb) bt
* thread #1, name = 'qbs-1684', stop reason = signal SIGBUS
  * frame #0: 0x000000082109fcad libQt5Script.so.5

    frame #8: 0x00000000002024a0 qbs-1684`_start(ap=<unavailable>,

Not sure if this is valid or not or how else I can help.
