Description Yoav Zach 2004-05-17 11:49:13 UTC
Description of problem:
when working in a system with fast system calls, ia32el crashes soon 
after the creation of a new thread. this is because libia32x.so fails 
to write the address of the fast-syscall kernel stub into the tls of 
the newly created thread.

Version-Release number of selected component (if applicable):
4600

How reproducible:
run MT 32 bit application on top of ia32el on a system with fast-
syscalls.

Steps to Reproduce:
1.
2.
3.
  
Actual results:
ia32el crashes

Expected results:
ia32el should work correctly
