Following the instructions of an older thread, I was able to make memcheck print the line that the warnings of interest actually take place. So, no need to have massif work without a segfault.
Now my question is: is it safe to ignore warnings like the following: ************************************************** ==19931== Warning: set address range perms: large range [0x17435040, 0x35b70280) (undefined) ==19931== Warning: set address range perms: large range [0x17435040, 0x35b70280) (defined) ==19931== Warning: set address range perms: large range [0x17435040, 0x35b70280) (noaccess) ************************************************** ? These are the only messages that memchecks reports, and I am not sure that I understand their difference...
