1// This test is for testing that the --threshold options in both Massif and
2// ms_print work as they should.  A threshold of 10% is a good choice for
3// this file, because in some parts of the tree it renders all children
4// insignificant, and in others parts of the tree it renders only some
5// children insignificant.
6//
7// Also, it's deliberate that the 'malloc(2000)' and 'my_malloc1(500)' calls
8// are in 'main' -- at one point, ms_print was failing to connect some
9// children arrows when a more significant child didn't have any children of
10// its own, eg:
11//
12//   |
13//   ->20.00% (2000B) 0x804846A: main (thresholds.c:43)
14//
15//   ->13.00% (1300B) 0x80483A4: my_malloc2 (thresholds.c:16)
16//
17// (There must be a '|' between the '->'s.)
