This is peculiar: "I am working on ... x86_64" but invoking "gcc -m32" which requests "generate code for i686". Also, if the value is not at least 4 then some generated SSE instructions (even on i686) will fault because they demand 16-byte alignment, and any call involving a variable number of arguments which includes any argument that requires 16-byte alignment will generate incorrect code. The best strategy is to omit "-mpreferred-stack-boudnary" entirely. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
