seqan: i386 build fails with compiler error

[ryandesign (Ryan Carsten Schmidt)]

Trying to build seqan on a 64-bit Mac with Snow Leopard and Xcode 3.2.6 and build_arch set to i386 results in a compiler failure:

/i386-10.6-mp/var/macports/build/_Users_rschmidt_macports_dports-clean_science_seqan/seqan/work/seqan-1.3.1/apps/mason/simulate_illumina.h:461: internal compiler error: Segmentation fault

I can report this bug to Apple, but I'm not sure how interested they are, since I doubt there will be any further changes to the gcc compiler or Xcode 3 from Apple.

Perhaps someone with Xcode 4 and/or Lion could test whether this is still a problem with llvm-gcc-4.2 and/or clang.

Why can't you try llvm-gcc-4.2 and clang with Xcode 3.2.6?

[ryandesign (Ryan Carsten Schmidt)]

I've now tested on Mountain Lion and had no problem compiling seqan for i386 or x86_64 with the default compiler, clang.

I can go back and see if using llvm-gcc-4.2 on Snow Leopard would work for the i386 build.

Should be fixed by r119902. See #43072.
