octace + exceptions

[Kai Habel]

Hello,

Is it possible to use exception handling in octave. I am trying to use
it an oct-file. sth. like

try {
        ...
} catch (...) {
        cout << "exception cought"
}

When I trigger an exception, octave dies with the following backtrace.

Program received signal SIGABRT, Aborted.
0x4073fc11 in __kill () from /lib/libc.so.6
Current language:  auto; currently c
(gdb) bt
#0  0x4073fc11 in __kill () from /lib/libc.so.6
#1  0x4073f81f in raise (sig=6) at ../sysdeps/posix/raise.c:27
#2  0x40741053 in abort () at ../sysdeps/generic/abort.c:88
#3  0x4070c3f5 in __default_terminate () from
/usr/lib/libstdc++-libc6.1-1.so.2
#4  0x4070c41a in __terminate () from /usr/lib/libstdc++-libc6.1-1.so.2
#5  0x4070ce5c in __throw () from /usr/lib/libstdc++-libc6.1-1.so.2
#6  0x805fe95 in main (argc=1, argv=0xbffff574) at octave.cc:590  

I compiled octave and the oct-file with -fexception instead of
-fno-exception.

I am new to this c++ feature. Is it possible to use exception handling
at all in octave? Do I have to set other compiler options?

Thanks in advance
Kai
