One difference that I noticed between machines where it's reproducible (e.g. Jessie) and a machine where it is not (e.g. openSUSE 13.1) is the PCRE library:
|
openSUSE 13.1 |
libpcre.so.1 => /usr/lib64/libpcre.so.1
|
|
|
libpcrecpp0-32bit-8.37-2.4.1.x86_64
|
libpcre1-8.37-2.4.1.x86_64
|
pcre-devel-8.37-2.4.1.x86_64
|
libpcreposix0-8.37-2.4.1.x86_64
|
libpcre1-32bit-8.37-2.4.1.x86_64
|
libpcrecpp0-8.37-2.4.1.x86_64
|
libpcre16-0-8.37-2.4.1.x86_64
|
|
Jessie |
libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.

but I don't know if all other warnings grow from it, and even if they do, what we should do about this.
