ltrace is not working properly on Ubuntu 15.04 ppc64el.
Example:
ubuntu at ubuntu1504:~$ ltrace `which ls`
__printf_chk(1, 0x3fffd36dce78, 0x3fffd36dce88, 0x3fffd36dcf28 <unfinished ...>
...
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
There is a patch that fixes this issue:
http://lists.alioth.debian.org/pipermail/ltrace-
devel/2014-February/001027.html
In order to get the ppc64el, the idea is to get the upstream tree and do a reset until commit eea4ad2cce289753aaa35b4e0258a76d8f8f367c
That would allow to create a patch of 27514 lines

** Description changed:
[Impact]
ppc64el users of ltrace.
- [Test case]
- See below.
+ [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.

Title:
Ltrace is broken on ppc64el
Status in ltrace package in Ubuntu:
Fix Released
Status in ltrace source package in Trusty:
In Progress
Status in ltrace source package in Wily:
New
Bug description:
[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.
---
ltrace is not working properly on Ubuntu 15.04 ppc64el.
Example:
ubuntu at ubuntu1504:~$ ltrace `which ls`
__printf_chk(1, 0x3fffd36dce78, 0x3fffd36dce88, 0x3fffd36dcf28 <unfinished ...>
...
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
There is a patch that fixes this issue:
http://lists.alioth.debian.org/pipermail/ltrace-
devel/2014-February/001027.html
In order to get the ppc64el, the idea is to get the upstream tree and do a reset until commit eea4ad2cce289753aaa35b4e0258a76d8f8f367c
That would allow to create a patch of 27514 lines
