Fixing problem with with studio 11

Question

Hello
I have problems using the fix command in studio 11
when I try to fix my program I get a warning and afterwards dbx crashes:
dbx >fix -v -f
/opt/Sun_Studio11/SUNWspro/prod/bin/cc -g -c -o testinfowin.o -I /v10.0/sources/include -D_POSIX_PTHREAD_SEMANTICS -v -DANSI -DSYS='UNIX_V' test.c -W0,-xp\$XAjQAqAhDgNGnrg. -c -o /tmp/dbx.fix.test.o.24753.464.6.o
"test.c", line 22: warning: Function has no return statement : main
/usr/ccs/bin/ld -G -o /tmp/dbx.fix.test.o.24753.464.5.so /tmp/dbx.fix.test.o.24753.464.6.o
dbx: warning: new function '' found in "test.c"
dbx: warning: new function '' found in "test.c"
handler (2) moved to "test.c":14
dbx: internal error: signal SIGSEGV (no mapping at the fault address)
dbx's coredump will appear in /tmp
Abort (core dumped)
The strange thing with this is, that there is no new function.
The problem doesn't occur with older Verions of dbx
Does any one know this problem or a solution?
Thanks
Clemens

Hello Maxim
thanks for your reply.
Looks like a bug in dbx, which I am not aware of...
It wouldn't hurt however to try to install latest
patches (both OS and Sun Studio ones):
http://developers.sun.com/sunstudio/downloads/patches/
ss11_patches.html
Maybe it is linker issue?
I have already installed patches
121023-04
109147-43
108434-22
121017-10
121015-04
Could you also post dbx stack trace here? It can be
obtained with
$ pstack /tmp/core
right after dbx has crashed. here is the output from pstack:
pstack /tmp/core

It would also be great
to have a reproducible test case if you can manage
it, of course.That' s a little bit difficult since I have to link about 11 libraries.
I don't know whether this helps you: I have written a short test program calling a function in a library It look like this
#include "osystem.h"
#include "userwin.h"
extern long InfoWindowInit(int openWindow, WINSRVFKT applMsgServer, CMDDISPATCH cmdWpFkt, ACCDATA accel, MENUDATA menu, short menuRet, char parFileName, long mode, long helpMsgNr, char *helpString);
int InfoMainMsgServer(long winId, int mode, int par, long lppar)
return 0;
int main(int argc, char ** argv)
char *parFileName = "test";
InfoWindowInit(0, InfoMainMsgServer,
(CMDDISPATCH)0,
(ACCDATA *)0,
(MENUDATA *)0,
(short *)0,
parFileName,
2,0,CNULL);
if I omit the declaration, I get a compiler warning, but i can fix.

And by the way, which version of Solaris you are
running?I am running Solaris 8
