 Hi.
 
 I changed the src/tests/lib/libc/tls/dso/Makefile, adding CFLAGS=-O0 to 
 disable optimization and built the tests using __thread int var4 = 1.
 
 Then I ran the test and the process froze and had to be killed.
 
 So I ran it again and used gdb on the process and I found that it was in the 
 same place as the debugging of calligrawords with the same values for 
 variables.  So for testing where it stops its better to disable optimization 
 in the Makefile for the libraries used for the tls dlopen test.
 
 Regards,
 
 Nat.
