Crash of Garbage Collection Work Queue if dylib is loaded on 10.8 applications and Garbage Collection is enabled #10

Open rtibdewal opened 11 years ago

If application in which we are injecting has following settings on 10.8 OSX Garbage Collection Work Queue will crash.

ARCHS = $(ARCHS_STANDARD_64_BIT) GCC_VERSION = com.apple.compilers.llvmgcc42 GCC_ENABLE_OBJC_GC = required //user defined setting.

On crash it will generate following message,

malloc: Thread::suspend(): unable to suspend a thread: err = 268435459, Thread 0x111000000: _pthread = 0x108129000, _thread = 0x8b07, _stack_base = 0x108129000, enlivening on, 0 local blocks

It will even when injected library has exactly same configuration as of the application in which we are injecting. After injecting play a little bit with application, like for 5-10 seconds.
