memprof got installed but fails with segmentation fault

[deepak]

memprof got installed.

uname -a
Linux foo-xen #1 SMP Mon Jan 26 03:09:12 UTC 2009 x86_64 GNU/Linux

But, i am getting "Segmentation fault" when i run the example from the README

ruby foo.rb
foo.rb:5: [BUG] Segmentation fault
ruby 1.8.7 (2010-04-19 patchlevel 253) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2010.02
Aborted

CODE:
require 'rubygems'
require 'memprof'
Memprof.track {
100.times{ "abc" }
100.times{ 1.23 + 1 }
100.times{ Module.new }
}

it is on a virtualized XEN instance.

[deepak]

it is working perfectly on a physical machine, the error is occurring on a xen based virtual machine.

I'm having the same problem.

deploy@staging:~$ uname -a

I'm getting a seg fault trying to use this Memprof::Tracer with OS X and REE

/gems/memprof-0.3.10/lib/memprof/tracer.rb:18: [BUG] Segmentation fault
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-darwin11.1.0], MBARI 0x6770, Ruby Enterprise Edition 2011.03

some times it comes across as a Bus Error, always on the same line:

Its failing for me as well. REE is installed on a physical machine with OS X 10.7.2 with REE 1.8.7

Same here with slightly later patch:

I'm hitting this too using Memprof.track and REE:

Also got this error on Mac OS 10.7.4 with REE, did anybody found a solution ?

I'm getting the same thing on REE on a Macbook Pro (Retina) using Mac OS X Lion 10.7.4 (11E2620):

Try to uninstall/reinstall the Gem. I had this issue and that fixed it for me.
