Hi, In an attempt to run an OpenGL application on CentOS 7 I've bumped on an "invalid pointer" crash in libstdc++. Details can be seen on this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1417663 Sorry for posting an external link, but in summary on CentOS 7 mesa is compiled against a specific llvm version which then is statically linked to libstdc++ (gcc 4.8.5). But my application uses a more recent gcc (5.4.0) and I ship a launcher script which always choose to run with the newest version. This approach works pretty well among many Linux distributions, but not in this case where a system library that I need is statically linked to libstdc++. So before digging into more details I would like to know: Is mixing a system library statically linked to libstdc++ with an executable dynamically linked to a newer libstdc++ expected to work at all? Thanks in advance for any help, Guilherme Quentel Melo
