Re: [mpich-discuss] MPICH-3.2: SIGSEGV in MPID_Request_create () at src/mpid/ch3/src/ch3u_request.c:101

      Can you send us a toy program that reproduces this problem?

I pulled from master (at d8bb1df from yesterday) again and then
recompiled with the --enable-g=most,mem flag instead of just
--enable-g=most.
The good news is that the --enable-g=most,mem flag compiled successfully.
The bad news is two-fold:
1. I believe I'm still getting the same SEGV as I was getting before
related to req->dev.ext_hdr_ptr       = NULL; (Although it's now
pointing to a different line in src/mpid/ch3/src/ch3u_request.c (line
56 instead of line 101 as before). I'm not sure if the line is
relevant; some other things may have moved around in that file since
then the 3.2 release version.
2. I no longer have debugging symbols in my library, so my backtraces
are not helpful. It's possible these two issues are related?
I did double check that I rebuilt my application from scratch so it
linked in the new library and that the library was indeed rebuilt (by
looking at file creation timestamps).
Any ideas about these two issues? Thank you.

Good catch! the `most` option implies `mem`, but the root configure failed
to forward the `mem` option to the MPL software layer. We will push a fix,
but meanwhile you can specify `--enable-g=most,mem` to get the desired
behavior.

I've tried both git HEAD (3ea7589) as well as the August 1 master
snapshot and am having trouble building it; I'm getting the same error
in both cases. I've configured with --enable-g=most but otherwise it's
all default. I'm running on OSX (Darwin - 15.6.0) and clang 3.8.1.
It's erroring on compiling src/mpi/attr/lib_libpmpi_la-attr_delete.lo
due to an issue with the macro MPL_free
Has anyone seen this before? I'm including the full error trace below:

This should be related to the alignment problem reported before
(http://lists.mpich.org/pipermail/discuss/2016-May/004764.html).
We plan to include a fix in the 3.2.x bug fix release series. Meanwhile,
please try the repo version (git.mpich.org/mpich.git), which should not
suffer from this problem.

Hello, I'm running into a segfault when I run some relatively simple
MPI programs. In this particular case, I'm running a small program in
a loop that does MPI_Bcast, once per loop, within MPI_COMM_WORLD. The
buffer consists of just 7 doubles. I'm running with 6 procs on a
machine with 8 cores on OSX (Darwin - 15.6.0 Darwin Kernel Version
15.6.0: Thu Jun 23 18:25:34 PDT 2016;
root:xnu-3248.60.10~1/RELEASE_X86_64 x86_64). When I run the same
program with a smaller number of procs, the error usually doesn't show
up. My compiler (both for compiling the MPICH source as well as my
application) is clang 3.8.1.
When I run the same program on linux, also with MPICH-3.2 (I believe
the same exact source), compiled with gcc 5.3, I do not get this
error. This seems to be something I get only with
gdb shows the following stack trace. I have a feeling that this has
something to do with my toolchain and/or libraries on my system given
that I never get this error on my other system (linux). However, it's
possible that there's an application bug as well.
I'm running the MPICH-3.2 stable release; I haven't tried anything
from the repository yet.
Does anyone have any ideas about what's going on here? I'm happy to
provide more details.
Thank you,
Mark
