I was able to reproduce Geoffrey's failure on Mac OS X 10.8, with LLVM
3.2. The stage2 compiler eventually segfaults ("Segmentation Fault
11") during the build process after being compiled successfully with
stage1.Something recently happened, because I was bootstrapping fine with LLVM 3.2 recently after David's fixes landed (I filed a small raft of tickets.) It's times like these I really wish we had a reliable 'git bisect'... I unfortunately haven't had time to dig into this, but I'll file a ticket to track it this morning. I can also reproduce this on my ARM/Linux machine. Previously, I got it to at least get done with stage2, and fail later in DPH. Now it seems to fail earlier in the same way the OS X build does. OS's: - 32bit ARM/Linux, Ubuntu 12.10 Linaro derivative; GCC 4.6.3. Bootstrapping compiler is GHC 7.4.1, LLVM 3.2. - 64bit OS X 10.8 Mountain Lion, llvm-gcc (XCode 4.6.) Bootstrapping compiler is GHC 7.6.2, LLVM 3.2. Also, @Jan: the warnings during the build process probably come from your bootstrap compiler. The built compiler (stage1/stage2) both support LLVM 3.2 directly and have correct version checks, but the bootstrap compiler you're using won't. In practice this mismatch never proved a problem in the past; just weeks ago the entire tree validated with the LLVM build on OS X with no failures and I was working on ARM things. I'll file a ticket and dig in soon when I get a chance.
