Can you also send the output of:
/usr/local/my-mpich-3.2/64bit/bin/mpichversion
/usr/local/my-mpich-3.2/64bit/bin/mpiexec -info
Something in your error output doesn't look right to me. I'm having a hard time finding the code that would execute a PMI command that causes the string buffer to overflow and omit a newline.

Dear MPICH staff,
in these days I was trying to download MPICH 3.2 and I've found this to be impossible. The links simply continue to redirect to the download page, but no download begins.
I've also tried to check the Installer Guide or other guides, but the links are broken too (error 404).
Can you please verify that your web site is working properly, please?
I suspect you have several links broken also in other pages.
Thanks.
Best regards.

Note that the problem doesn't show up when building MPICH in any normal manner - what I'm doing is unpacking the static libraries libmpi.a and libpmpi.a on Mac and re-packaging all the object files into a single .dylib file - and that fails because of the duplicate symbols.
Cheers,
Edric.

Thanks, I believe I've seen this issue before but our nightly builds don't currently show any errors. Might be specific to a compiler/linker version.
Do you have a patch you could share to show your fix? If not, I will try to reimplement the solution.

All links should now be restored.
