<pre>Created <span class=""><a href="attachment.cgi?id=21596" name="attach_21596" title="test.cpp">attachment 21596</a> <a href="attachment.cgi?id=21596&action=edit" title="test.cpp">[details]</a></span>
test.cpp
On FreeBSD the attached testcase triggers the errno=2 (No such file or
directory):
<span class="quote">> 71779 io CALL open(0x4065e0,0x601<O_WRONLY|O_CREAT|O_TRUNC>,0666<S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH>)
> 71779 io NAMI "a/b"
> 71779 io RET open -1 errno 2 No such file or directory</span >
But the error message printed through the exception std::ifstream::failure
doesn't contain this information:
<span class="quote">> ios_base::clear: unspecified iostream_category error</span >
Why is it "unspecified"?
It should say exactly what happened.
FreeBSD 11.2.</pre>
