Hi,

Thanks for your patience.  GDB v5 does not build nicely for me on the
Netwinder, so I have to use gdb with undemangled names.

(Still not sure if this is a GCC problem or a GNUStep problem.)

Running any application from Gnustep gives me results as follows:

Program received signal SIGSEGV, Segmentation fault.
0x4023f8ec in objc_msg_lookup (receiver=0x204d658, op=0x40220084) at
objc/sarray.h:230
(xxgdb) stack
Undefined command: "stack".  Try "help".
(xxgdb) info stack
#0  0x4023f8ec in objc_msg_lookup (receiver=0x204d658, op=0x40220084) at

_i_NSConcreteTimeZoneDetail__initWithTimeZone_withAbbrev_withOffset_withDST_
() from
/opt/GNUstep/System/Libraries/armv4l/linux-gnu/gnu-gnu-gnu/libgnustep-base.so.1

(xxgdb)

And it shows it failing at:

filename: /opt/gcc/gcc/armv4l-unknown-linux-gnu/libobjc/objc/sarray.h
Line number: 230

static inline void* sarray_get_safe(struct sarray* array, sidx index)
{  <<==== fails at exactly this point.
  if(soffset_decode(index) < array->capacity)
    return sarray_get(array, index);
  else
    return (array->empty_bucket->elems[0]);
}

#endif /* __sarray_INCLUDE_GNU */


Thank you,

Robert
