Subject: Re: Crash in bitcoin 0.1.0
To: hal.finney@gmail.com I isolated the problem.  If I spawn a thread and do mapAddresses.count, even as the very first thing in the program, it segfaults.  The workaround is to needlessly call mapAddresses.count in the main thread once and it's fine from then on.  I hate to blame the compiler, and I've never had a GCC compiler bug before, but this feels like one.  Maybe some bit of init code it tries to optimize out if it's not called at least once in the same thread, or some STL optimization that's not thread friendly.  I'm really dismayed to have this botch up the release after all that stress testing. The attached file: bitcoin-0.1.1.rar (filesize 2,132,686) is the version where I deleted the mapAddresses.count line, and that should be the safest version.  (that was the only use of mapAddresses.count)  If you could try this version and confirm that the crash is fixed, I'd appreciate it.
