Github doesnt seem to accept new accounts:  "There were problems creating your account." It gives no further details, so I dont know how to get on there.

The platform is CentOS 5.6 x64.  The cause of the problem is unknown.  It started shortly after 2am CET this morning, and is probably related to whatever has been received around that time (because it worked for almost a day before).  I have posted everything that I have, which is (-debug -printtoconsole).  There was another piece of information which I didnt save unfortunately.  It a crash report after the first crash, and it contained a call stack dump.  The initial cause for the crash was a "free" of invalid memory.  I have another similar box that also crashed tonight, but it did not dump the callstack and it did have less problems to start again.  Therefore the other problems are probably caused by data that has been saved during the initial problematic event, and in fact the first box only came up again after deleting all cached data in .bitcoin/ and in particular the addr.dat file.

So there must be at least three problems, one is that an invalid memory free can be triggered, another one is that the file parsers can bail out fatally when encountering corrupt file content, and the third problem is that normal operation can cause files be filled with such corrupt content.

Let me know what else you need to know from me.
