probleam about ThreadLocalImpl of llvm

Hi, everyone:
I am very sorry to trouble you, but I need your help about my problem about ThreadLocalImpl in llvm of 2.8 version. I have compiled it in Windows xp with mingw, and have compiled skyeye(an open source project about simulator) as it uses llvm. But when I run a testcase ---- arm_hello, it came out segment fault. I used gdb.exe to trace it, it gave the following infomation:

At last, I print some information in ThreadLocalImpl function:

44 ThreadLocalImpl::ThreadLocalImpl() : data(0) {
45 pthread_key_t* key = new pthread_key_t;
46 printf(“IN %s, line = %d key: 0x%x\n”, FUNCTION, LINE, key);
47 int errorcode = pthread_key_create(key, NULL);
48 printf(“In %s, line = %d\n”, FUNCTION, LINE);
49 assert(errorcode == 0);
50 (void) errorcode;
51 data = (void*)key;
52 }

It print the following information:

$ /opt/skyeye/bin/skyeye.exe -n -e arm_hello
IN ThreadLocalImpl, line = 46 key: 0x3e2c68


I am very sorry to trouble you, but I need your help about my problem about
ThreadLocalImpl in llvm of 2.8 version.

this is a very old version of LLVM, I suggest you try something newer, eg the
recently released version 3.1.

Best wishes, Duncan.

  I have compiled it in Windows xp with

I want to use a newer version, but skyey expect to use version 2.8.
