Hi all,

I've found case when clang consumes much more memory that GCC (maybe it's a memory leak)

Attachement is preprocessed translation unit from amalgamated Botan library.

clang++ -c -O0 botan.ii                   # OK
clang++ -c -O2 botan.ii                   # Memory usage reaches 1Gb and continues to grow
clang++ -S -emit-llvm -O2 botan.i   # OK
llc -O2 botan.s                               # OK
