Bug 483629

Description of problem:

Firstly: I'm not sure where the problem actually lies - could be glibc, could be gcc, could be invalid testcase. I'm filing this so it won't get lost in the case it's a real bug we would want to fix in RHEL4. NOTABUG is expected, but I want to be sure.

When testing bug 479630, I've encountered a SEGV on the testcase provided by customer, on something like this, if present in a shared library compiled with -fPIC:

static __thread char whatever[100];

void do_stuff(){
   printf("whatever=%p\n", whatever);
}

Because I haven't seen the SEGV on other arches, and even RHEL5 on ia64, I assumed it's a bug. I've tried to narrow down the issue, but I'm not sure if the reductio is valid, so I will append both testcases.

Version-Release number of selected component (if applicable):
gcc-3.4.6-10.ia64
glibc-2.3.4-2.41.ia64

How reproducible:
always

Steps to Reproduce (original reproducer)
1) untar the TLS.tar.gz
2) cd TLS; make
3) LD_LIBRARY_PATH=. ./ldmain

Steps to Reproduce (my reduced reproducer)
1) untar the tc.tar.gz
2) cd tc
3) make test-fpic-thread
  
Actual results:
SEGV

Expected results:
no SEGV
