[Bug c++/31941] New: [4.1/4.2/4.3 Regression] "confused by earlier errors" message without earlier error message

[tbm at cyrius dot com]

With the attached source, 4.0 prints and error and then says that it got
confused by earlier errors.  In 4.1 and 4.2, however, it gets confused
without actually printing the earlier error:

This is on ia64.  Apparently x86_64 shows an error.  Can someone confirm what
I see on ia64?

/home/tbm/src/digikam-0.9.1/./digikam/libs/widgets/metadata/iptcwidget.cpp:159:
error: request for member 'c_str' in '

?

so there seems to be an error.  Of course we probably ICE during error
reporting
which may confuse this matter ;)
