dtrace discuss - May 2008 - Translating addresses when program is dead

Hi,

This is not strictly a dtrace question, but I would like to find the
function names corresponding to a list of addresses once a process is dead.
I understand that using the -p option of dtrace helps avoid that need in the
first place but I keep running across situations where I only get the
addresses and the binary (e.g. pstack from core on Solaris 10 where the
addresses did not get translated due to a pstack bug).

Is there some utility in Solaris to do that (a bit like the gnu addr2line
but for binaries without debug symbols) ? Or should I just nm the binary and
find the matching functions? addr2lin

  Thanks a lot and sorry if this is a bit off topic.

For a core file, pstack and mdb should always get the right symbols  
unless the binaries have changed. Adding the symbol table to the core  
file content can further ensure that symbols will come out correctly;  
check out coreadm(1M).

Hi,

I was trying to work without the core file. The solution is actually fairly
simple : just dbx <executable> and examine the addresses that I want
resolved.

It''s not as easy as addr2line but almost.

  Thanks a lot,
