Are you shure the binary runs stable? AFAAIK you really need the -fpic flag to compile against newer Qt5 versions (unless you compiled Qt yourself and disabled Qt's "reduce relocations"). From Qt's changelog: - On x86 and x86-64 systems with ELF binaries (especially Linux), due to a new optimization in GCC 5.x in combination with a recent version of GNU binutils, compiling Qt applications with -fPIE is no longer enough with GCC 5.x. Applications now need to be compiled with the -fPIC option if Qt's option "reduce relocations" is active. For backward compatibility only, Qt accepts the use of -fPIE for GCC 4.x versions. Note that Clang is known to generate incompatible code even with -fPIC if the -flto option is active. Applications using qmake or cmake >= 2.8.12 as their build system will adapt automatically. Applications using an older release of cmake in combination with GCC 5.x need to change their CMakeLists.txt to add Qt5Core_EXECUTABLE_COMPILE_FLAGS to CMAKE_CXX_FLAGS. In particular, applications using cmake >= 2.8.9 and < 2.8.11 will continue to build with the -fPIE option and invoke the special compatibility mode if using GCC 4.x.
