make check failed on Mac OS X 10.7.3 w/clang -O4

[近藤 充弘]

hi gmp project,

I encountered failure while make check on Mac OS X with clang -O4(see below).
Because make check was succeeded with -O0, -O1, -O2 and -O3 options,
this might be a bug of clang compiler related LLVM system.
I attached several logs, is there anything else which i can do?

regards,

--- optimization options summary of clang compiler
       -O0 -O1 -O2 -Os -Oz -O3 -O4
           Specify which optimization level to use.  -O0 means "no
           optimization": this level compiles the fastest and generates the
           most debuggable code.  -O2 is a moderate level of optimization
           which enables most optimizations.  -Os is like -O2 with extra
           optimizations to reduce code size.  -Oz is like -Os (and thus -O2),
           but reduces code size further.  -O3 is like -O2, except that it
           enables optimizations that take longer to perform or that may
           generate larger code (in an attempt to make the program run
           faster).  On supported platforms, -O4 enables link-time
           optimization; object files are stored in the LLVM bitcode file
           format and whole program optimization is done at link time. -O1 is
           somewhere between -O0 and -O2.
