Problem with the implicit module finding system used for the packages on github.

I have a problem with one (three, actually) of the APEX unit tests. If the following code fragment is compiled as a SaC module, with -doinl, the function testthornXIB (marked as "inline" in its header, btw) it dies in execution. With -noinl, it works properly.

crud.sac UTThornBoolean.unittest.sac

First, we generate a module from crud.sac, AND make the module name crud:

ls
crud.sac  UTThornBoolean.NOTME.sac  UTThornBoolean.unittest.sac
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ grep MODNM *.sac
crud.sac:module MODNM;
UTThornBoolean.unittest.sac:use MODNM: all;
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c crud.sac -maxoptcyc 2 -DMODNM=crud 
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c UTThornBoolean.unittest.sac  -maxoptcyc 2 -DMODNM=crud -doinl
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ a.out
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  2>
< 1  1 > 
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c UTThornBoolean.unittest.sac  -maxoptcyc 2 -DMODNM=crud -noinl
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ a.out
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  2>
< 1  1 > 

So far, so good. Now, we use a different module name:

apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ rm -r a.out* tree/ host/
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c crud.sac -maxoptcyc 2 -DMODNM=notcrud 
warning: Module/class 'notcrud` should be in a file named "notcrud.sac" instead of "crud.sac"
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c UTThornBoolean.unittest.sac  -maxoptcyc 2 -DMODNM=notcrud -noinl
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ a.out
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  2>
< 1  1 > 
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c UTThornBoolean.unittest.sac  -maxoptcyc 2 -DMODNM=notcrud -doinl
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ a.out
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  1>
< 1 > 
Dimension:  1
Shape    : <  2>
< 1  1 > 

Still good. The module Warning appears harmless. Let's try again with yet another module name:

apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ rm -r a.out* tree/ host/
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c crud.sac -maxoptcyc 2 -DMODNM=UTThornBoolean 
warning: Module/class 'UTThornBoolean` should be in a file named "UTThornBoolean.sac" instead of "crud.sac"
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c UTThornBoolean.unittest.sac  -maxoptcyc 2 -DMODNM=UTThornBoolean -doinl
a.out
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ a.out


*** SAC runtime error

apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ sac2c UTThornBoolean.unittest.sac  -maxoptcyc 2 -DMODNM=UTThornBoolean -noinl
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTThornBoolean/src/crud3$ a.out
1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
0

This is strange in two ways:

1. Using -doinl causes the runtime to crash.

2. Using -noinl causes the code to execute, BUT it is not the code in the function in crud.sac.

So, it appears that we are pulling .so files from somewhere other than this folder. Where?
