The following appears as a bug to me that results in a bus error on
the efi332 target for the test program psxsem01....
in seminit.c:36, _POSIX_Semaphore_Create_support() is called with an explict
NULL value for "name".
in semaphorecreatesupp.c:110 _Objects_Open of
_POSIX_Semaphore_Create_support() is called with the NULL valued
"name" for arg 3.
This in turn calls _Objects_Copy_name_string() in
objectcopynamestring.c through the inline function _Object_Open. This
tries to copy a null terminated string from source (a NULL pointer in
this case) to destination..... SEGV (no RAM/ROM at 0x0000 in the test
configuration I'm using)...
psxsem01 runs fine for me if I replace _Objects_Copy_name_string()
with the following code to trap the NULL source pointer (just an
example and quick fix... maybe not the best place to trap
the NULL).... Something's not right here....
*(char *)destination++ = *(char *)source;
} while ( *(char *)source++ );
