Hello,
I've been trying to get Sword 1.7.3 (crosswire.org/sword) running on Alpine.
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== Command: diatheke -b KJV -k Ps117
==5743==

==5743== 
==5743== HEAP SUMMARY:

==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

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
