--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> 2010-12-09 18:46:28 UTC --- This got reported to us in https://bugzilla.redhat.com/show_bug.cgi?id=657606 but no details about whether it was pristine or modified libdecnumber and which version thereof. GCC shouldn't ICE even on invalid input (especially when it doesn't say that it is invalid), so some form of error message would be useful.
