The bug might have been there forever, but it only got apparent due to some unrelated (most likely: VM) changes. The sad thing is that it ain't easy to debug. The symptom is that the machine is hard-resetting without a whisper, instead of falling back into DDB. The only method i could think of were single-stepping or ``breakpointing forward'' through the imgact_gzip code, but oh well, this will most likely require slightly more than an hour... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
