Sword is a library for free bible software that comes with a few utilities. It builds fine and runs with few issues, but I'm having a bit of trouble figuring out one of the bugs: valgrind was recommended, but I can't get valgrind to run the command properly. I was asked to provide the output of roughly this command (adjusting for Windows/*nix differences): valgrind --leak-check=full --track-origins=yes \ --keep-stacktraces=alloc-and-free \ utilities/diatheke/.libs/diatheke -b KJV -k Ps117 But when I do this, diatheke errors out: ----- $ valgrind --leak-check=full --track-origins=yes --keep-stacktraces=all oc-and-free diatheke -b KJV -k Ps117 ==5743== Memcheck, a memory error detector ==5743== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==5743== Using Valgrind-3.9.0 and LibVEX; rerun with -h for copyright info ==5743== Command: diatheke -b KJV -k Ps117 ==5743== diatheke: cannot load -b: No such file or directory ==5743== ==5743== HEAP SUMMARY: ==5743== in use at exit: 0 bytes in 0 blocks ==5743== total heap usage: 0 allocs, 0 frees, 0 bytes allocated ==5743== ==5743== All heap blocks were freed -- no leaks are possible ==5743== ==5743== For counts of detected and suppressed errors, rerun with: -v ==5743== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) ----- Comparing this to the default output below, my guess is that the command line parsing is not happening when run from valgind. The bug I'm trying to track down (background): diatheke is a utility that comes with Sword that shows all verses or passages in a bible or book that match a key (such as a reference); the basic command line looks like this: diatheke -b book -k reference The bug is that the last passage/verse gets repeated: $ diatheke -b KJV -k Ps117 Psalms 117:1: O praise the LORD, all ye nations: praise him, all ye people. Psalms 117:2: For his merciful kindness is great toward us: and the truth of the LORD endureth for ever. Praise ye the LORD. : For his merciful kindness is great toward us: and the truth of the LORD endureth for ever. Praise ye the LORD. (KJV) Currently running Alpine edge with linux-vanilla as kernel. All binaries are built using abuild; the system CFLAGS were "-Os -pipe -fomit-frame-pointer", but the package adds "-O3". I got the same results after changing CFLAGS in abuild.comf to "-g -pipe". If the build scripts are desired, I can supply them. Thanks, Isaac Dunham
