Hi ,
I Installed Ubuntu16.04 In PowerNV and try to run ltrace ls or ltrace ps it will fail with segfault .
Reproducible Step :
1- Install Ubuntu16.04 in PowerNV or as KVM or as PowerVM
2- Install ltrace package
3- Try to run ltrace with any userspace utility like "ltrace ps"
Actual Result :
Throw Seg fault
Expected :

The problem is related to procps-ng 3.3.10
Upgrade to procps-ng 3.3.11 solves the issue
Going to Mirror and ask Canonical to advise.

This bugs is linked to procps-ng 3.3.10 known as having some issues. Is upgrade to 3.3.11 an option ? |
[Impact]
ppc64el users of ltrace.
[Test cases]
- ltrace `which ls`
- ltrace /bin/ls /usr
- ltrace ps
- ltrace make (building ltrace itself, for instance)
[Regression potential]
While the changes should fix some of the more common uses of ltrace, the added/modified methods and options may break for some specific calls on ppc64el, or on other architectures (powerpc, arm) which are affected by the changes.
ARM was already failing with the available version of ltrace; this would not change the behavior on ARM.
