[Llvm-bgq-discuss] 2 quick questions about upgrading

[Biddiscombe, John A.]

Hello list

I'm still using r209570-20140527 from early last year and have started more serious development on BGQ (rather than on IO nodes as previously).

I cannot debug my programs with totalview because the clang produces 'incompatible' binaries. (and I can't use gdb either because gdb server gives me "invalid packet reply" errors which I haven't managed to resolve).
Q1 : Are there any changes in newer bgq clang releases that solve this totalview binary problem (such as using newer libs or some other link changes)

I've got a problem where code runs in debug mode, but I have a segfault in release mode. Looks like some var is being optimized out when it should not.
Q2 : Are there any known bug or fixes that might encourage me to try a newer clang to get around this. (I haven't ruled out a problem with my own code, but it's looking like a compiler glitch to me at the moment)

Thanks

JB
