Sorry I can't offer a solution but I can confirm this as an issue.

I used to get this on our old work hardware;
CPU AMD athlon 2100+ (single core at 1733Mhz IIRC) PC3200 DDR.

Since upgrading (Q6600 quad core at 2.4Ghz, DDR2 667Mhz?) I'm not getting this
any more. [Rubs lucky rubber chicken to avoid the kiss of death].

This suggests it may be a subtle timing issue which will be tricky to find.

I got into the habit of running top after the reconfig. If one of the squid
owned processes hits 100% CPU, kill with extreme prejudice. Actually I still
do this.

IIRC it was the old squid process which did this, but I could easily be wrong.
If you can confirm that it may help one of the developers to find the
problem.
