Severity of "Bailed out without a bailout address" error using --enable-debug?

Hi! I have recently compiled PHP 5.0.0 from one of the CVS snapshots on an IBM eServer pSeries machine running AIX 5.2.0.0 ML3, but found out that configuring PHP with the --enable-debug directive yields the following error on e.g. most of the built-in tests: ---- EXPECTED OUTPUT abc ---- ACTUAL OUTPUT abc /usr/local/src/php5-200408020630/main/main.c(1694) : Bailed out without a bailout address! ---- FAILED My question is -- what does this bailout error mean, what could have caused it, and how severe is it? Should I worry about it, or just skip --enable-debug? The tests (and other scripts) seem to be working fine except for the debug "notice". Thanks in advance! Best regards, Björn Wiberg P.S. I have tried PHP 4.3.8 as well; --enable-debug works fine using that version, i.e., gives no bailout errors. D.S.
