Errors ".sdata section mapping" when Valgrind starts on PowerPC platform
I've been trying to use VG v3.6.0 for the first time, on a cross-compiled PowerPC platform.
I compiled VG from the sources, and when installed I used non-stripped versions of ld-2.3.2.so and libc-2.3.2.so to avoid the well-know strlen problem,
I get the following errors when VG starts up. :
--491-- WARNING: Serious error when reading debug info

Can anyone help me?
