I just found this posting through a Google search and I couldn't find a
followup or further information. Thus, for the sake of anyone else
searching for this: this error comes from ctfconvert(1), when converting
debug information for a struct or union ("sou") which has more than 1023
members. It looks like the 1023 limit is an inherent limit in the encoding
used by CTF; there's no constant that can just be increased as a workaround.
The error causes ctfconvert(1) to terminate, so the corresponding source
file will end up with no CTF data and hence dtrace will not work correctly.
It looks like vxge_hal_mrpcim_reg_t is the only struct that triggers this
error, so the impact is limited to 16 files in the vxge(4) driver
(Exar/Neterion X3100 10GbE).
