Hi,     I used the "--enable_profile" option to configure my MonetDB and ran "make clean; make; make install".     I, then, started my MonetDB instance and ran the following query:         select count(*) from lineitem where l_partkey > 9000;     Lastly, I quit from the "mclient" session and issued "monetdbd stop ...".      I observed that there are several gmon.out files in different directories in my top build directory.     Therefore, I issued the following gprof command:         gprof /usr/local/bin/mserver5 ./sql/backends/monet5/gmon.out ./gdk/gmon.out  ./monetdb5/extras/mal_optimizer_template/gmon.out ./monetdb5/modules/atoms/gmon.out             ./monetdb5/modules/kernel/gmon.out ./monetdb5/modules/mal/gmon.out ./monetdb5/scheduler/gmon.out ./monetdb5/optimizer/gmon.out ./monetdb5/mal/gmon.out      However, the output of the above command did not show any calling sequence containing the execution of MAL instructions.     Did I miss anything?     Thanks in advance.
