--- Comment #1 from amajer at suse.de ---
Created attachment 411649
  --> https://bugzilla.nasm.us/attachment.cgi?id=411649&action=edit
proposed patch

A much simpler reproducer is simply this,

    db  1e-20
    dw  1e-80

when the negative exponent overflows causing buffer under-run. I've marked the
reproducer as obsolete, since above 1 or 2 lines is enough to trigger this.
