 not exactly the version shipped with 10.6.8, more like installed by hand:

# which bash
/opt/local/bin//bash

 well, thats strange, but it means that this also should do the trick,
without setting PROMPT_COMMAND:

# i=0; while [ $i -lt 25 ]; do history -a; history -n; let i++; done;

it actually does for me, anything above 24 in the upper limit of the
above loop triggers the issue (no PROMPT_COMMAND set anywhere).
 at the same time, the same loop does nothing out of the ordinary on
linux/i386 with bash--version:
#bash --version
GNU bash, version 4.3.30(1)-release (i686-pc-linux-gnu)
