Please do. I'm glad it's being so useful - it seems to be hitting a
surprising amount of bugs of different origins.
It might be an idea
I read the MPICH trac ticket you pointed to and your analysis seems pertinent.
The impact of my patch for “count = 0” has a similar outcome to yours: removed
all references to the datatype if the count was zero, without looking fo the
special markers.
Let me try to come up with a fix.
Thanks,

Hello,
I think I've come across a bug when using ROMIO to read in a 2D distributed
array. I've attached a test case to this email.
In the testcase I first initialise an array of 25 doubles (which will be a
5x5 grid), then I create a datatype representing a 5x5 matrix distributed
in 3x3 blocks ove
12 matches
