Профилирование процесса с ограниченной памятью с помощью valgrind

Я использую new_handler в C ++ попытаться освободить часть памяти при сбое выделения. Можно ли использовать массив таким образом, чтобы профилировать это? Я хотел бы видеть, сколько памяти фактически освобождается обработчиком и в идеале иметь подробный снимок до и после вызова new_handler,

Простой вызов массива в процессе не работает, потому что он ограничен тем же пределом, что и программа:

> cat run
#!/bin/bash
ulimit -v 128000
my_program

> valgrind --tool=massif --trace-children=yes --detailed-freq=1 ./run

==7605==     Valgrind's memory management: out of memory:
==7605==        newSuperblock's request for 4194304 bytes failed.
==7605==        122073088 bytes have already been allocated.
==7605==     Valgrind cannot continue.  Sorry.
==7605==
==7605==     There are several possible reasons for this.
==7605==     - You have some kind of memory limit in place.  Look at the
==7605==       output of 'ulimit -a'.  Is there a limit on the size of
==7605==       virtual memory or address space?
==7605==     - You have run out of swap space.
==7605==     - Valgrind has a bug.  If you think this is the case or you are
==7605==     not sure, please let us know and we'll try to fix it.
==7605==     Please note that programs can take substantially more memory than
==7605==     normal when running under Valgrind tools, eg. up to twice or
==7605==     more, depending on the tool.  On a 64-bit machine, Valgrind
==7605==     should be able to make use of up 32GB memory.  On a 32-bit
==7605==     machine, Valgrind should be able to use all the memory available
==7605==     to a single process, up to 4GB if that's how you have your
==7605==     kernel configured.  Most 32-bit Linux setups allow a maximum of
==7605==     3GB per process.
==7605==
==7605==     Whatever the reason, Valgrind cannot continue.  Sorry.
