Follow-up Comment #2, bug #23727 (project gnustep):

Thank you for the quick reply!

About question 2:
I have configured and compiled gnustep-make and gnustep-base using the
--enable-native-objc-exceptions. The @address@hidden blocks do catch
exceptions, except if it is raised after a forwardInvocation call.

I have also tried to use the NS_DURING, NS_HANDLER, and NS_ENDHANDLER macros,
with the same results. I think that native exception handling works for me in
the normal way, only not through a forwardInvocation call. Could this be
related to the ffcall library?

my compiler:
gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13)
Copyright (C) 2006 Free Software Foundation, Inc.

gnustep-base-1.14.1 and gnustep-make-2.0.2 is compiled from source.

To justify that it works the following program correctly catches the
exception I raise, but fails to catch the execption comming from the
NSDictionary object.

 #include <Foundation/Foundation.h>

int main(){

  NSString *key1 = @"one";
  NSNumber *key2 = [NSNumber numberWithInt: 2];

  NSString *value1 = @"firstValue";
  NSString *value2 = @"secondValue";

  NSMutableDictionary *dict = [NSMutableDictionary dictionary];

  [dict setObject: value1 forKey: key1];
  [dict setObject: value2 forKey: key2];

  @try {
    [NSException raise: @"TestException"
                 format: @"Just testing"];
  address@hidden(NSException *e){
    NSLog(@"%@", e);
  @try {
    NSLog(@"dictionary: %@", dict);
  address@hidden (NSException *e){
    NSLog(@"%@", e);

  [pool release];
  return 0;
