From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030922 Description of problem: Running bison on this three line input file %% some_identifier: %% results in a segmentation violation. Version-Release number of selected component (if applicable): bison-1.875-4 How reproducible: Always Steps to Reproduce: 1.bison ah.y Actual Results: bash-2.05b$ bison ah.y Segmentation fault Expected Results: A correct (if pretty uninteresting) ah.c parser. Additional info: This does not happen on i386. It happens on x86_64. I'm aware omitting the final semicolon from rules is considered obsolecent. For a while bison warned about it, but that seems to be gone again. In any case, it should not crash.
This is fixed by upgrading to version 1.875c, which will be in the next erratum.
