I have recently discovered a problem with shared libraries created on
solaris 8 X86. To me it seems that it is a bug introduced in an OS
patch, since I don't have the same problem on some of my more or less
unpatched systems. I have been able to create a small example to
reproduce the problem:

trondn@solsrv2 cctest> uname -a
SunOS solsrv2 5.8 Generic_108529-29 i86pc i386 i86pc

trondn@solsrv2 ~> cc -V
cc: Sun WorkShop 6 update 2 C 5.3 Patch 111680-09 2003/05/18

trondn@solsrv2 cctest> make
cc -v -c main.c
cc -v -c -g -KPIC func.c
cc -v -c -g -KPIC func_ver.c
cc -v -o libfunc.so -G func.o func_ver.o
cc -v -o testprog -R. -L. main.o -lfunc

trondn@solsrv2 cctest> dbx -V testprog
Sun WorkShop 6 update 2 Dbx Debugger 6.2 Patch 111684-14 2003/10/21
Reading testprog
Reading ld.so.1
Reading libfunc.so
dbx: panic: "Objfile::objname"(): Assertion (lo->syms_read) failed -
"objfile.cc":1419

I have attached the files I used to track down the problem.

Note that if I add a funtion to func_ver.c the problem disappears...

I downloaded (and installed) the latest OS recommended patch-cluster
today, but I still have problems :(

   return val * 2;
}

static const char *version = "\nlibfunc.so V1.0.0\n";

extern int func(int);

int main(int argc, char **argv)

   return func(2);
}
