[mpich-discuss] mpich-master-v3.2-331-g44fd9c5f39e5: runtime error spawning processes

[Min Si]

Hi Siegmar,

It seems it is still caused by the unaligned memory access issue in 
MPICH. Unfortunately, the fix patch is still in our reviewing queue. I 
hope it can be pushed to master as soon as we can. Please check this 
ticket for tracking the status (it will be closed once we have pushed 
fix to master). Thanks.
