Hey, i just want to ask if i found a bug in the gcc5.2 or not. I have created a really simple test-setup which causes a crash of my component before the execution of main(). The crash happens during dynamic lib loading time. I have a Library A compiled without -std=c++11 and a executable B with -std=c++11. >From my understanding the newly introduced ABI compatibility should prevent the linking if some ABI inconsistencies exist. I using a fresh ubuntu15.10 in a VirtualBox. The only thing that the lib does is include a boost header. The minimal example which failed can be found here: https://github.com/goldhoorn/sandbox/tree/gcc5.2-issue Testcase5 with clang works without any problem. Is this the intended behavior of gcc of did i found a bug? Best, Matthias Goldhoorn -- Dipl.-Inf.
