Since 1.4.4, I have experienced consistent lockups in the Nether dimension. This is usually associated with the death of a Ghast, or with the explosion of a Ghast fireball. I am playing on a remotely served game. This did not occur prior to 1.4.4, and happens with a vanilla minecraft.jar. Affects 1.4.4 and also 1.4.5. When the game crashes, the CPU of javaw.exe pegs at 25% and memory holds steady (usually around 600MB to 1GB).

Try updating your java to the most recent version.
Duplicate of MC-2749.
Updated 1.6 to 1.6_37 and 1.7 to 1.7_09. Still crashes. This does not appear to be a duplicate of MC-2749, as java does not crash. It simply consumes all available CPU and the game freezes. Also, this does not happen in a split second, it ALWAYS correlates to a ghast fireball explosion.

If it does not crash then don't say it crashed. Freezing and crashing are 2 different things. During gameplay please hold down F3 + C for a few seconds and forcibly crash the game, then attach the resulting crash report.
Ah, sorry about that. Updated description and attached crash-2012-11-26_17.01.49-client.txt. Crash report was taken with OptiFine running, I can revert to vanilla if you need that (crash problem still evident in vanilla 1.4.5).

Are your video card drivers up to date?
Yes. 306.81, latest available for my OS.

Do you run the game with smooth lighting on or off? (and have you tried the opposite setting?)
Smooth lighting at 100%, Graphics on Fancy with Fast Advanced OpenGL. I will try toggling smooth lighting (and other options) to see what the results are and will report back. Thanks!
I reverted to vanilla 1.4.5, tried all combinations up to graphics=fast, smooth lighting=off, advanced opengl=off, view bobbing=off, particles=minimal, and the game still froze.

I'm not that familiar with Java... my basic attempts at trying to run minecraft under Java's debug environment are proving fruitless. Is there something I'm missing in running "jdb minecraft -Xms512m -Xmx1024m", or is this not doable due to the obfuscation? It would be great to be able to examine the stack trace when this happens.
Figured it out. Launched minecraft with JDB attached. Found this on the console window of java.exe:
Error in class 'CodecJOrbis'
Secondary Ogg header corrupt in method 'readHeader'.
Error in class 'CodecJOrbis'
Error reading the header
This is the output of "threads" from jdb at the time of the freeze:

It would appear that one of the explode.ogg files in the random folder is corrupt. I replaced all 4 with the chicken hurt1.ogg and it works. I must have something corrupt as those are all restored at the startup of minecraft. Will experiment with wiping out the bin folder tomorrow.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
XP is supposed to have at least Service Pack 3 for Minecraft to work properly.
No answer on query, assuming fixed.
Still resides in 1.5.
