Hi,
I have a problem with an libobjc2 updated versions. 
The compilation runs without the problem.  However during starting a program
an error appears: 
# cd Clang/
# gdb hello3
GNU gdb 6.8 qnx-nto (rev. 411)
..........
(gdb) set solib-search-path /usr/pkg/lib
(gdb) start
Temporary breakpoint 1 at 0x804880f: file hello.m, line 31.
Starting program: /root/Clang/hello3
Temporary breakpoint 1, main () at hello.m:31
31              myGreeter=[Greeter new];
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.

...........................................

I ask for where to search for the error.
