Shared library call problems on PowerPC with gdb 7.2

Hello,
I'm trying to debug a shared library on PowerPC (P3041).
Unfortunately it is nearly impossible to step through
functions in the shared library, cause neither "next" nor "step"
work as expected. e.g. I set a breakpoint at a function in the shared
lib and when I try now to step through the code (with "next" or "step")
I get:
"Single stepping until exit from function call___do_global_ctors_aux,
 which has no line number information."

I can return with "finish" to my function, but the same thing happens
for every "next" or "step".

I found a few reports about this problem from 2007 and 2008 (but it
seems as if they were solved long ago), e.g. from Ulrich Weigand:
http://sourceware.org/ml/gdb-patches/2008-04/msg00639.html

I'm using gdb 7.2, the exact version is:
GNU gdb (Wind River Linux Sourcery G++ 4.4a-341) 7.2.50.20100908-cvs
Maybe the gcc/binutils version is also relevant:
powerpc-wrs-linux-gnu-gcc (Wind River Linux Sourcery G++ 4.4a-341) 4.4.1

Thanks

Klaus
