--- Comment #7 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> 2012-12-10 12:43:42 UTC --- Now, compilation seems to go fine, but I'm not figuring out how to do it properly so it works at run time. I have: > gfortran -g -fsanitize=thread -fPIE PR55561.f90 > ./a.out FATAL: ThreadSanitizer can not mmap the shadow memory (something is mapped at 0x400000 < 0x7cf000000000) FATAL: Make sure to compile with -fPIE and to link with -pie. next try yields > gfortran -g -fsanitize=thread -fPIC -Wl,-pie PR55561.f90 /data/vjoost/gnu/binutils-2.22/install/bin/ld: error: /usr/lib/../lib64/crt1.o: requires unsupported dynamic reloc 11; recompile with -fPIC /data/vjoost/gnu/binutils-2.22/install/bin/ld: error: /data/vjoost/gnu/gcc_trunk/install/lib/gcc/x86_64-unknown-linux-gnu/4.8.0/crtbegin.o: requires dynamic R_X86_64_32 reloc against '__TMC_END__' which may overflow at runtime; recompile with -fPIC Is there something wrong in the way I configured gcc or do I need a different command line ? ../gcc/configure --prefix=/data/vjoost/gnu/gcc_trunk/install --enable-languages=c,c++,fortran --disable-multilib --enable-plugins --enable-lto --disable-bootstrap
