Description:   Last confirmed: Opened: 2004-06-05 00:43 
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.

I think this is a dup of bug 15761.

------- Comment #3 From Wolfgang Bangerth 2004-06-07 21:04 ------- 
This testcase here doesn't ICE on x86, apparently only on PPC, while 
the one in PR 15761 also affects x86. The bug may or may therefore not 
be duplicates. We'd need someone with a PPC box to reduce the testcase.

I failed to reproduce the bug from crosscompiler.

------- Comment #5 From Wolfgang Bangerth 2004-06-07 22:46 ------- 
OK, thanks Zdenek. Ren'e, do you have a chance to test on a bigger machine?

3.3-hammer, 3.4.1, and 3.5.0 powerpc64-linux -m32 don't ICE for me.

------- Comment #7 From Andrew Pinski 2004-06-10 13:14 ------- 
Closing as fixed then as no one can reproduce it.
