Currently, --ignore-fn is only matched with the top IP entries that have a fnname. With this change, we first search for the first IP that has a fnname. This e.g. allows to ignore the allocation for a stacktrace such as: 0x1 0x2 0x3 fn_to_ignore otherfn This is then used in massif c++ tests new-cpp and overloaded-new to ignore the c++ libstdc++ allocation similar to: ==10754== 72,704 bytes in 1 blocks are still reachable in loss record 10 of 10 ==10754== at 0x4C2BBCD: malloc (vg_replace_malloc.c:299) ==10754== by 0x4EC39BF: ??? (in /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.22) ==10754== by 0x400F8A9: call_init.part.0 (dl-init.c:72) ==10754== by 0x400F9BA: call_init (dl-init.c:30) ==10754== by 0x400F9BA: _dl_init (dl-init.c:120) ==10754== by 0x4000C59: ???
