PROGRAM main CHARACTER(LEN=24) :: a(2) a = '' END PROGRAM These variations run OK: - Not built with -Og - Assignment is to scalar instead of array - Assignment is a space character - Assignment to element of the array This is a regression I am seeing in 12.1.0 but did not get with 11.3.0. Tested on MinGW (Windows 10) and Manjaro with GFortran 12.1.0. The error message I get on Windows is: Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
