# IRC, freenode, #hurd, 2011-12-04
<mcsim> defpager uses it's own dynamic memory allocator, which uses
vm_allocate/vm_deallocate as backing store? Am I able to use duma in such
case?
<braunr> you will have to adapt it
<braunr> but it's already designed to handle custom allocators
<braunr> iirc
<braunr> btw, are there special flags for that memory which the pager
allocates ?
<braunr> e.g. to use wired memory ?
<mcsim> yes, wired memory
<braunr> you'll have to change that in duma then
<braunr> but apart from such details, it should be straightforward
<antrik> braunr: I have no idea about duma; but if you think it's a useful
tool, please add it to open_issues/code_analysis.mdwn
<antrik> (I guess we should have a "proper" page listing useful debugging
tools...)
## IRC, freenode, #hurd, 2012-09-03
<mcsim> hello. Has anyone tried some memory debugging tools like duma or
dmalloc with hurd?
<braunr> mcsim: yes, but i couldn't
<braunr> i tried duma, and it crashes, probably because of cthreads :)
## IRC, freenode, #hurd, 2012-09-08
<mcsim> hello. What static analyzer would you suggest (probably you have
tried it for hurd already)?
<braunr> mcsim: if you find some good free static analyzer, let me know :)
<pinotree> a simple one is cppcheck
<mcsim> braunr: I'm choosing now between splint and adlint
