I'm not sure if this is an error specific to my Mac or all Macs, but any program I run (even a blank program) automatically crashes whenever I drag and drop a directory onto it. It doesn't matter what's in the directory either.
Before the program crashes, it prints a single line of text to the Terminal saying "Trace/BPT trap: 5". I also tested to see if the love.directorydropped callback is called before the program crashes and it isn't.
I was able to obtain a crash log from my Mac's system.log file which says:
Oct 4 16:13:00 75-112-94-220 com.apple.xpc.launchd (org.love2d.love.17272): Service exited due to signal: Segmentation fault: 11 sent by exc handler
This only happens on 0.11.0 (not 0.10.2) and isn't happening on Windows either.
