ltrace is not working properly on Ubuntu 15.04 ppc64el.
Example:
ubuntu@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

# of expected passes 348

[Impact]
ppc64el users of ltrace.
[Test case]
See below.
[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.

[Impact]
ppc64el users of ltrace.
[Test case]
See below.
[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@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

[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@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
