<pre>The code is as follow:
# 3 "<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED WORKSFORME - Linking two .a files explicitly on the command line fails"
href="show_bug.cgi?id=3">bug3</a>.cc"
class Z {
public:
Z(int);
private:
int i;
};
Z::Z(int j=43): i(j){}
int main()
{
Z zobject=Z();
}
clang++ produces the following errors:
<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED WORKSFORME - Linking two .a files explicitly on the command line fails"
href="show_bug.cgi?id=3">bug3</a>.cc:12:10: error: addition of default argument on redeclaration makes this
constructor a default constructor
Z::Z(int j=43): i(j){}

<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED WORKSFORME - Linking two .a files explicitly on the command line fails"
href="show_bug.cgi?id=3">bug3</a>.cc:7:2: note: previous declaration is here
The code comes from a gcc bug report:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=2189">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=2189</a>
A previous version of g++ also rejects the above code, but it is fixed.</pre>
