97
|
|
|

|

|
98
|
|
|
|
|
|
|
B is a memory leak finder for C programs, implemented in |
99
|
|
|
|
|
|
|
Perl. It uses GDB to walk internal glibc heap structures, so it can |
100
|
|
|
|
|
|
|
work on either a live process (the first synopsis) or a core file |
101
|
|
|
|
|
|
|
(the second synopsis). |
102
|
|
|
|
|
|
|
|
103
|
|
|
|
|
|
|
Compared to Valgrind, Purify, or various malloc debugging libraries, |

is very slow, |

|
111
|
|
|
|
|
|
|
=item * |
112
|
|
|
|
|
|
|
does not provide stack traces showing how memory was allocated, |
113
|
|
|
|
|
|
|
|
114
|
|
|
|
|
|
|
=item * |
115
|
|
|
|
|
|
|
does not work on multi-threaded programs (although this could be fixed). |

However B is much easier to use in a production environment |
120
|
|
|
|
|
|
|
(rather than a test environment) because the program under test |
