Confirmed on IB too. Appears to be a ROMIO/ad_pvfs2 bug. Noncontig
in file, contig in mem. App writes 10 mb but romio calculates 20 mb
and issues a request that tries to access unallocated memory. See
ad_pvfs2_write.c line 502: st_fwr_size = 20m. Perhaps that should
be f_data_wrote? Or perhaps calculation of fwr_size is wrong?
