well, I installed glib as --universal, meaning that it contains both 32 bits and 64 bits binaries. And actually, I removed the 64 bit binary (using the lipo function), because Director is a 32 bits application and all Xtras (plugins) are also. So we are really running in 32 bit here. Even on MacOSX10.8, which is a 64 bits kernel, but which can run 32 bits applications.
And, this instruction does _not_ crash on my MacOSX10.8 machine, and _does_ crash on another MacOSX10.8 machine. I found another possibility : AVX. I found on the net (http://stackoverflow.com/questions/16389207/llvm-jit-tutorial-code-crashes-with-simple-parameterized-function-why) a similar SIGILL LDS, which was actually caused by an VEX-prefixed AVX instruction, which neither the processor nor the disassembler knew about, and interpreted as an LDS. And AVX is available on my machine, and not on the two crashing machines… I'm investigating this now. Trying to compile glib without AVX.
