$(basename $0) <leaksFile> [<options>] [<excludePatterns>]
<leaksFile>
A file containing the allocations with stack traces from
the guarded heap output.
To generate such a file run a program with the following
environment variables prefixed and pipe the output to a file:
LD_PRELOAD=libroot_debug.so MALLOC_DEBUG=ges50 program > file
The number after the "s" is the stack trace depth. Note that
there is an implementation defined maximum.
--no-default-excludes
Do not exclude known statics and globals. By default a list of
excludes is used that removes known allocations that are never
freed by the system libraries.
--no-exclude-empty
Do not exclude allocations with no stack trace. By default
allocations without a stack trace are excluded. This should
only happen for very early allocations where the stack trace
setting has not yet been applied. The program should not be
able to generate such allocations.
<excludePatterns>
Exclude allocations that match a regular expression. The
expression is matched against the whole text block of the
allocation, so can match in the header line as well as any
stack trace lines. Note that the whole block is on a single
line and newlines have been replaced with the caret (^)
character.
Multiple exclude patterns can be specified as one argument each
and they will be ored to form the final expression.
