dbx: internal warning writable memory segment of size 0

Question

While trying to load a core file using dbx I get the following warning:

dbx: internal warning: writable memory segment 0xfa8b0000[16384] of size 0 in core

There doesn't seem to be an explanation in:

(dbx) help core

What does this message mean?

EDIT

The rest of the output:

core file header read successfully
Reading ld.so.1

dbx: internal error: signal SIGBUS (invalid address alignment)
dbx's coredump will appear in /tmp
Abort (core dumped)

And dbx exits without loading the core.

Was the core file generated on the same machine ? Is the core file truncated for some reason ? — jlliagre, Feb 13 '13 at 16:29
The core file was generated on the same machine. Not sure if it's truncated, the size is more than 400M. How do you tell? — Andrejs, Feb 13 '13 at 19:49
Do you have issues with debugging using core file outside that warning message ? — jlliagre, Feb 13 '13 at 22:04
Seems like a bug in dbx. You can try to open the core using mdb: `mdb core` — Mustafa Ozturk, Feb 14 '13 at 21:57

Got solved by upgrading Solaris Studio to version 12.3 and using the newer dbx from there.

One of the reasons why this could happen is because dbx expects the absolute path to get the object files, try giving the

dbx <PATHTOBINARY>/binaryfile

Of course, you can upgrade dbx to the latest version to fix the same.
