--- Comment #15 from anlauf at gcc dot gnu.org --- Created attachment 54006 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54006&action=edit Modified testcase I found that I get a hang on my system when I specify -fopenmp. It appears that there is a deadlock due to the evaluation of the merge arguments during the print. So changing the testcase as attached might fix the problem. Can you please verify?
