Hello,

we are porting code from Windows to Linux (Suse 7.3),
Gnat 3.14p on both platforms.
We do not get a symbolic traceback on linux.
The windows options are

gnatmake -s -cargs -O3 -bargs -f -E -largs ... ....adb

The options for Linux are

gnatmake -s -cargs -O3 -funwind-tables -bargs -f -E -largs ... ....adb

my exception handler looks like

exception
    when E : others =>
        Put(Ada.Exceptions.Exception_Information(E) &
              Gnat.Traceback.Symbolic.Symbolic_Traceback(E));

On windows I get an output like

Call stack traceback locations:
0x5dbb11 0x5dbe9e 0x5df0a6 0x5de42b 0x40166d 0x401103 0x77f1b9e8

0040166D in ?? at crt1.c:0
00401103 in ?? at crt1.c:0
77F1B9E8 in ?? at fake:0

but on linux only the adresses are given.
Whats wrong?

 Thanks for any hints.
