Bug#959767: wfmath: Please update symbols files for recent gcc on s390x

[Steve Langasek]

Package: wfmath
Version: 1.0.2+dfsg1-6
Severity: normal
Tags: patch
User: ubuntu-devel at lists.ubuntu.com

Hi Olek,

In Ubuntu, the wfmath package has started failing to build on s390x because
some additional C++ template symbols are now being inlined there with the
current gcc.

The attached patch fixes the build failure, by marking these symbols
optional - as is generally correct for any C++ template symbols.

I have not tried to reproduce this build failure on s390x in Debian, so I
don't know if it happens with the version of gcc that's current in unstable;
therefore I have only filed this bug at severity: normal.  However, at some
point this is likely to become a serious build failure in Debian as well, if
it isn't already.

Thanks,
