I ran it through valgrind by diverting indicator-session-service and
replacing it with the following script:
#!/bin/bash
exec valgrind \
--tool=massif \
--alloc-fn={g_slice_alloc,g_malloc,g_realloc} \
--massif-out-file=$HOME/massif-dump/indicator-session-service.out.%p \
/usr/lib/x86_64-linux-gnu/indicator-session/indicator-session-service.distrib \
"$@"
Running ms_print on the output files gave me some stack traces of the
highest number of unfreed allocations:
60.92% (1,262,577,672B) (heap allocation functions) malloc/new/new[],
--alloc-fns, etc.
