[Bug c++/15829] New: ICE on Botan-1.3.13 due to -funroll-loops

["rene at rocklinux-consulting dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling vanilla Botan-1.3.13 on PowerPC with -funroll-loops does ICE g++ 
3.4.0 (x86 not affected). 
 
How to reproduce: 
g++ -funroll-loops -fpermissive base64.ii 
 
-O1 and -O2 ICE; however -O0 and -O3 builds fine ... 
 
src/base64.cpp: In member function `void 
Botan::Base64_Encoder::encode_and_send(const Botan::byte*, Botan::u32bit)': 
src/base64.cpp:43: internal compiler error: in do_SUBST, at combine.c:446 
 
Of course I'll attach the preprecessed source.
