Hi, I've fixed the integrity check now. If you are still seeing aborts, then we have a serious lifetime problem*. If this is the case, try running with APR_POOL_DEBUG_VERBOSE. When you hit an abort, it will print: INVALID <address>
You can then scan back through the output for the address to see where it was DESTROYed (and CREATEd). Sander *) Or a bug in the debug code...
