<p class="MsoNormal">Hello list<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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).<o:p></o:p></p>
<p class="MsoNormal">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)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">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)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<o:p></o:p></p>
