[Bug 1644048] Re: 4.3-7ubuntu1.6 FTBFS on arm64 only with format-security error

[Julian Andres Klode]

** Description changed:

- This weirdly only fails on arm64.
+ [Impact]
+ Breaks build on arm64 in trusty:
  
  ../.././builtins/../.././builtins/help.def:130:7: error: format not a
  string literal and no format arguments [-Werror=format-security]
  
- The attached debdiff will be uploaded to trusty-proposed soon.
+ [Test case]
+ Check it builds
+ 
+ [Regression potential]
+ Indefinitely low.
+ 
+ [Other info]
+ The same code works fine on all other architectures and newer releases, but it seems broken anyway: We are passing the return value of ngettext() to printf() as the format string, which is unsafe.
+ 
+ We should evaluate why that works elsewhere and probably also do the
+ same fix in other branches, but I'll leave that to someone else to
+ decide. My intention here is to just get the trusty SRU for bug 1644048
+ building on all platforms.

** Changed in: bash (Ubuntu Trusty)
       Status: Confirmed => In Progress
