Hello,

> More or less. Lots of applications crash randomly here, mostly with bus errors coming from the bowels of libpthread. Sometimes there are segfaults too, but rarely. For some reason I can't even get a useful stack trace, usually it's something like this:
> Program received signal SIGBUS, Bus error.
> [Switching to LWP 1]
> 0x0000000041e0ef80 in pthread__sa_recycle () from /usr/lib/libpthread.so.0

> Error accessing memory address 0x872: Invalid argument.
