Laser50	Long title. But has anybody managed to get this to work on the latest, if not beta build on linux? (Ubuntu Server, mainly). Whenever I run it with that parameter, it just freezes up the whole thing and it doesn't ever start. So I can't really debug the crashed I'm experiencing. Which is quite annoying :\

Just for anyone who doesn't know,

Added the option -unsafe_diag to unblock SIGUSR2 even during lengthy I/O or possible infinite loop situations. Ordinarily, the signal may be blocked during this time to prevent it from interrupting a system call. It is generally not advisable to run all the time with this option due to the risk of interrupted system call. But if the game is behaving strangely and DreamDaemon does not respond to SIGUSR2 (a likely sign of an infinite loop), this option may help.

Laser50	I know what the function does, I was in need of it to backtrace a crash I've been having. But I guess I'll have to dig around some more and see if it may be related to me. Note: I found this: http://www.byond.com/forum/?post=1443427 And the last two, SIGSEGV and SIGBUS can be used without the need of said parameter. So I'm good for now.
