7zip - Valgrind massif produces no profile output for 7-Zip -

i want use valgrind massif figure out heap memory used 7-zip. when run massif on 7-zip, produces no output. here's command.

valgrind --tool=massif /usr/bin/7z filename.7z filename 

i expect output file named massif.out.pid within current directory no such output produced. should add that, using massif on other compression tools gzip, bzip2, compress, etc. produces massif.out.pid file.

i used valgrind -v , there no helpful information there either.

any thoughts on why doesn't work 7-zip?

/usr/bin/7z wrapper script.

#! /bin/sh exec /usr/lib/p7zip/7z "$@" 

try running

valgrind --tool=massif /usr/lib/p7zip/7z filename.7z filename 

instead.
