Runtime error : invalid pointer [UBUNTU16.04 GCC6]

[ThibaultGROUEIX]

I tried to compile Mitsuba v5 (with qt4 cause qt5 is complaining about QtWidget) on Ubuntu 16.04 with gcc 6, using the fix mentionned in https://github.com/mitsuba-renderer/mitsuba/issues/7 Everything went fine except I get an invalid pointer error at runtime. the trace is :

Any idea what it might be due to ?

I am also getting the same error. However, I disabled the Qt4 module and compiled without it and I am using mitsuba from the command prompt. So, I believe that Qt4 might not be the reason. My log is copied below:

Same here. Centos 7 cluster, even without any Qt. Did any of you manage to solve the problem?

I think it is probably due to a mismatch between the C++ ABI used to compile the dependencies (e.g. OpenEXR or even boost) and mitsuba itself. I recompiled the dependencies with _GLIBCXX_USE_CXX11_ABI=0 and then compiled mitsuba also with this flag and it worked.
