Currently, ext2fs.static fails as follows:
(gdb) rr

To be precies, it fails in libstore/argp.c:find_class() since
__start_store_std_classes and __stop_store_std_classes simply don't
exist (i.e. they don't point to anything valid):
(gdb) b find_class
Reading in symbols for ../../src/libstore/argp.c...done.
Breakpoint 1 at 0x807041e: file ../../src/libstore/argp.c, line 240.
(gdb) rr
Breakpoint 1, find_class (name=0x81115ff "query", classes=0x0)
at ../../src/libstore/argp.c:240
240 for (cl = classes ?: __start_store_std_classes;
(gdb) p __start_store_std_classes
Address of symbol "__start_store_std_classes" is unknown.
(gdb) p __stop_store_std_classes
Address of symbol "__stop_store_std_classes" is unknown.
So we end up doing the following which is simply wrong:
(gdb) n
241 classes ? *cl != 0 : cl < __stop_store_std_classes;
(gdb)
247 if (! classes && store_module_find_class)
(gdb)
251 return cl;
(gdb)
255 }
And from here, everything goes bonkers. What should happen in in
find_class() if everything is wroking as it should is:
(gdb) b find_class
Breakpoint 1 at 0x8072fb2: file
/build/mbanck/hurd-20050513/build-tree/hurd/libstore/argp.c, line 240.
(gdb) dir /home/ams/hurd/src/libstore

at /build/mbanck/hurd-20050513/build-tree/hurd/libstore/argp.c:240

240 for (cl = classes ?: __start_store_std_classes;
(gdb) p __start_store_std_classes
$1 = 0x8128bc4
(gdb) p __stop_store_std_classes
$2 = 0x8128bf4
(gdb) n
0x08073043 240 for (cl = classes ?: __start_store_std_classes;
(gdb)
243 if ((*cl)->name && strcmp (name, (*cl)->name) == 0)
(gdb)
244 return *cl;
(gdb)
255 }
And we return something sane in CL. Pointers to a soultion are
welcome.
Phew...
