--- Comment #5 from Jan André Reuter <j.reu...@fz-juelich.de> --- I tried to compile and run the source code I uploaded when creating the ticket. I used the latest daily bump: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=53ef7c1d9a44a2c681d4b3433a853cd4461be8c5 The program compiles without issues now and runs correctly when adding a main function.
