bt not printing source file or lines

[David Terry]

HI,
I just recently subscribed to this group so I'm not sure if this has been
addressed already.

I'm working on a project that uses shared libraries.  I'm running gdb
version 5.0 on hpux11.11

I start gdb and set the path to point to my ojbect files and the dir to
point to my source files.  I have compiled everything with the -g option
and nothing is stripped of symbols.

I set a breakpoint in main and when my libraries are loaded I set a break
in my specific function.  It seems to break at this point but when I do a
bt I get the following:


(gdb) bt
#0  0x7a8dc5a0 in ?? () from /tmp/dterry/45507/libatriaks.sl
#1  0x7a86d4ec in ?? () from /tmp/dterry/45507/libatriatbs.sl
#2  0x7a6eb0d8 in ?? () from /usr/atria/shlib/libatriaview.sl
#3  0x7a190ce8 in ?? () from /tmp/dterry/45507/libatriacmd.sl
#4  0x7a19045c in ?? () from /tmp/dterry/45507/libatriacmd.sl
#5  0x7a0876fc in ?? () from /tmp/dterry/45507/libatriacmdsyn.sl
#6  0x7a06bcf8 in ?? () from /tmp/dterry/45507/libatriacmdsyn.sl
#7  0x7a06c170 in ?? () from /tmp/dterry/45507/libatriacmdsyn.sl
#8  0x7a3dac28 in ?? () from /usr/atria/shlib/libatriatool.sl
#9  0xd3e4 in main ()
#10 0x7a98d6bc in ?? () from /lib/libc.1

why is the ?? showing up, why can't gdb tell what file and what line it is
currently in?  If I type l I get

(gdb) l
1       end.c: No such file or directory.

it doesn't give me the next ten lines from where it breaks.  I have
verified that the shared libraries are getting read in from the right
directories.  any thoughts?  wondering if this is a bug.  thanks,

below is a complete execution of my gdb session.
