[Bug c++/15463] New: ICE in do_SUBS

[jkillius at arcor dot de]

Hello, 
there is an ICE with valid code and -funroll-loops in crypto++ 
g++ -g -march=athlon64 -mtune=athlon64 -O3 -funroll-loops -save-temps -c 
asn.cpp 
asn.cpp: In static member function `static void 
CryptoPP::OID::EncodeValue(CryptoPP::BufferedTransformation&, long unsigned 
int)': 
asn.cpp:200: internal compiler error: in do_SUBST, at combine.c:446 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
make: *** [asn.o] Error 1

I can't reproduce this on x86 linux: I get a lot of warnings/errors about 
too large constants, and even after fixing them the compiler just happily 
compiles this code. Will probably need someone with an x86_64 box to test.

Ad reproducing: use x86_64 crosscompiler.

Anyway, patch:

That is because it is part of the mainline of GCC.
