[Llvm-bgq-discuss] bgclang r205936-20140409 on vesta/mira

John,

Yes, this looks exactly like the issue that really motivated the switch. There are necessary symbols that are just missing from the old 4.4.6 libraries (the situation is somewhat complicated because the compiler actually generated multiple version of these destructors, and the older gcc did not generate all of them). As I said, please let me know if you can't get the files.

 -Hal
