Hi,
where can I find "version 77592165aa3"? I have only the following
archives after the release of mpich-3.2.tar.gz.
I misunderstood your setup.  I thought you were working directly from 
our git repository, not from git snapshots.  If you were working from a 
repository, you would do this:

  $ git checkout -b 3.2.1-77592165aa3 77592165aa3
...
loki mpich-3.2.1 113 ls -C1 *.gz
mpich-master-v3.2-42-g67631a5c0e9e.tar.gz
mpich-master-v3.2-87-g7150bbc02ec8.tar.gz
mpich-master-v3.2-88-gbbb40df74d46.tar.gz
g7150bbc02ec8 is too old to contain my changes.  g67631a5c0e9e might 
be the one to try.
...
I've attached both config.log files from my gcc and cc version.
config.log-gcc says the unw_backtrace symbol exists in libunwind, but 
there is no libunwind.h header file on your system.  Looks like I need 
to be more careful in how I detect support for backtrace libraries.
...
I've searched for "libunwind tools" for our Linux version. It seems that
they are available for "Suse Linux Enterprise Server", but I didn't find
them for "Suse Linux Enterprise Desktop", which we use for most of our
machines. Shall I ask our Admin to install them?
what is supposed to happen is we look for several ways to generate a 
backtrace, then use the one we found.  What's bothering me is that we 
think we found libunwind, but when we try to use libunwind's features we 
fail to compile.  our configure should not report that libunwind is 
available if it is unusable.

For example, our configure also found the backtrace_symbols and 
backtrace_create_state functions.  These are often part of GCC, or maybe 
standalone in the libbacktrace package.  On your system (as is common on 
many systems) there is no backtrace.h

I will send you a patch to try out that will only use libunwind if it 
finds both the header file and the symbols.

Hi,
today I tried to build mpich-master-v3.2-88-gbbb40df74d46 on my machine
(SUSE Linux Enterprise Server 12.0 x86_64) with gcc-5.2.0 and Sun C
5.13.
I used the following command to build the system for gcc.
This looks like the "portable backtrace" functionality I added
recently.   Maybe I need to work on the "portable" part
of that.
MPICH thinks your environment has the libunwind tools, and so it is
trying to use libunwind to display the backtrace.
Unfortunately there's one more complication: a reorganization of the
MPL sources (commit 12c912ec6372).
If you can provide me with two pieces of information that would be great:
- what if you check out MPICH from a few weeks back?  I want to rule
out the source reorg, and if you check out version
77592165aa3, that will have just my changes and none of the reorg
changes.
- Can you send me your src/mpl/config.log ? (not the config.log from
top-level mpich, but the config.log subconfigure
from src/mpl)  I would like to see what backtrace libraries configure
found in your environment.   Then I can reproduce
it on my end.
