Sorry for beeing unclear. If I have done the compilation in 32 bit mode (the default in my config), the generated executable run fine. Then I can use the generated info to compile with -fprofile-use in 64 bit mode (-m64). gcc does not complain about this dirty trick (I have no idea if it is supposed to work) and produces an executable that fails to run. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34483
