Thanks for taking > the time to look at this. There is an unexpected (or rather missing) behaviour in the trace you have provided. You should find lines such as: --3143-- Reading syms from /home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_core-amd64-linux.so ... --3143-- Reading syms from /home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_massif-amd64-linux.so
Without these, there is no chance to have replacements being done. Maybe an installation problem ? Can you try: valgrind --tool=massif --soname-synonyms=somalloc=NONE --trace-redir=yes \ -v -v -v -d -d -d ./MyProg 2>&1 | grep -i preload This should give something like: --31179:2:initimg preload_string: --31179:2:initimg "/home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_core-amd64-linux.so:/home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_massif-amd64-linux.so" --31179-- Reading syms from /home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_core-amd64-linux.so --31179-- TOPSPECS of soname NONE filename /home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_core-amd64-linux.so --31179-- Reading syms from /home/philippe/valgrind/valgrind-3.8.1/install/lib/valgrind/vgpreload_massif-amd64-linux.so You should then check that the files referenced by initimg exist and have correct permissions (typically -rwxr-xr-x). If initimg is correct and files are existing and have correct permission, then mystery is increasing. You could try the same with memcheck and see if the preload for memcheck is working (and malloc replacement is properly done). You could also verify if the regression test for the static malloc replacement works by doing: cd memcheck/tests/ make static_malloc algrind --tool=massif --soname-synonyms=somalloc=NONE --trace-redir=yes \ -v -v -v -d -d -d ./static_malloc 2>&1 | grep -i preload Philippe ------------------------------------------------------------------------------ Keep yourself connected to Go Parallel: VERIFY Test and improve your parallel project with help from experts and peers. http://goparallel.sourceforge.net _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
