 Dear Fred,

 Thank you for your reply.
 I tested by substituting my own svn build (clang, gnustep) with
Philippe Roussel's Ubuntu packages build and llvm.org/apt build.
His build configured with non-fragile and non-debug worked well.
However, trying to build svn version still makes the same error.
 Here is gbd backtrace log ("b [NSException raise]" did not worked") :

 If this trouble did not occur in your configulation, please ignore this
not to waste your time as only my configulation would have some defects.

 Sincerely yours,
 Lee, Seong-Gu ( at gmail dot com )

















PS) Belows are my stupid test configuation which can be neglected.
However, it is thanksful for anyone to find any faults. I cannot confirm
these occur at any environemnt.

 As build switches are suspected, varied configurations were tested.
"1." is fragile abi and non-debug, "2." is non-fragile abi and non-debug
configuration and "3." is non-fragile abi and debug-default.

To summerize tests below,

                        non-debug               debug-default

                        "1."

                gworkspace : build OK
                             execute OK

                        "2."                            "3."
