Statically linked binaries killed by signal 9 on Yosemite

[Qianqian Fang]

hi everyone

I have compiled a set of binaries on previous versions of Mac (mostly 
OSX 10.6) with macports gcc/g++ using static linking, and thought that 
these binaries will be supported in the future versions of MacOS. 
However, several users of my software package reported failure on 
Yosemite. They received "killed by signal 9" error and the binaries can 
not be started. I haven't upgraded my Mac to Yosemite. Wondering if 
anyone can provide any insight what might be wrong.

One sample binary can be downloaded from this link:

http://sourceforge.net/p/iso2mesh/code/HEAD/tree/trunk/iso2mesh/bin/cgalmesh.mexmaci64?format=raw

despite the suffix, this file is actually a native executable compiled 
on Mac for x86_64 processors. If you run

file cgalmesh.mexmaci64

you will see "cgalmesh.mexmaci64: Mach-O 64-bit executable x86_64". The 
output of "otool -L cgalmesh.mexmaci64" shows it is a statically linked 
executable.

However, when you run "./cgalmesh.mexmaci64", it is immediately killed 
by the OS. This only happens on Yosemite.

Does anything know what might be wrong?

thanks
