--- Comment #1 from Jürgen Reuter <juergen.reuter at desy dot de> --- Ok, here is a bit shorter test case, untar the attached file, do ./make. This produces an executable seg_prod. With r222305 I get the desired result: $ ./seg_prod | ============================================================================ | Running self-test: beams | ---------------------------------------------------------------------------- Running test: beam_1 ... success. Running test: beam_2 ... success. Running test: beam_3 ... success. with r222439 I get: $ ./seg_prod | ============================================================================ | Running self-test: beams | ---------------------------------------------------------------------------- Running test: beam_1 Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
