Hi,

i am using latest musl git version,
when i trying to build llvm-3.3, i got follow error message:

../llvm/configure --prefix=/usr --build=x86_64-linux-musl
make
...
Linking Debug+Asserts executable clang
/llvm-build/Debug+Asserts/lib/libLLVMCodeGen.a: could not read symbols:
Memory exhausted
collect2: error: ld returned 1 exit status
...

my previous llvm compilation was succeed about 3 weeks ago,
although it got runtime error, but build was fine.

musl git version works fine, because, compile & install util-linux-2.23.1
was fine.

gnu ld ran out of memory as usual
(i dont think this issue is musl related)

google had the same problem so they wrote the gold linker
(you can try that, it's in binutils)

you can also try the magic flags
-Wl,--no-keep-memory,--reduce-memory-overheads
(this will make linking even slower)

you can try to run ld under valgrind to see if there are leaks
and report the bugs to binutils

alternatively buy more ram

or report the bug to llvm that their code is too bloated
