Hi all, I have a bug which appears to be GNU toolchain related. I reported this bug to LTTng mailing list here: http://lists.lttng.org/pipermail/lttng-dev/2014-April/022950.html The root cause appears to be a change in the way the GNU linker treats the __start_SECNAME symbol, which occured between 4.6.4 and 4.7.2. The only documentation for this feature that I was able to find was on gcc-help mailing list: http://gcc.gnu.org/ml/gcc-help/2010-04/msg00113.html I have some questions: 1) Is __start_SECNAME feature documented in more detail anywhere? 2) Why did the __start_SECNAME symbol move from local to global scope between 4.6.4 and 4.7.2? Any other insight into this issue would be very helpful. Thanks, Martin
