Can't fault someone for > working towards that goal. +1 to Warner's sentiments. gdb in base doesn't work well with threads (6.x never did ;/..), and lacks s= upport for other things (like python debugging). Being able to debug threads= reliably is a make or break thing. So while I understand and in general agree with you Rod, I completely disagr= ee on the practical end of things. I'm actually kind of curious as to why th= is isn't being done globally.. but I assume that it was described in one of t= he many threads some time ago about the status quo for debugging with gdb on= tier-two architectures.
