This triggers a bug in src/glx/x11/glxcurrent.c : The TLS variable __glX_tls_Context is compiled with the TLS model initial-exec, which is only ment for executables. Used in shared libraries, it can break TLS usage in other shared libraries. One example is when libGL is linked beforce libstdc++ in another library, which is then loaded via dlopen(). In this case, the TLS variables in libstdc++ aren't properly initialized, and it will segfault when trying to allocate an exception. I think there are 2 possible solutions: 1. Do not compile with --enabgle-glx-tls 2. Patch mesa to remove the tls-model attribute. I assume this will eat up the performance gain of TLS, since initial-exec is meant as an optimisation for apps not using the GL over dlopen directly or indirectly.
