      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)
