Hailey, I tried with your file and with debugging on and saw the following message: WARP: Recompute out extent with CHECK_WITH_INVERT_PROJ=TRUE I read through the code in gdalwarp.cpp and it seems this is something added, perhaps by Even, to check that the output area selected is appropriate and can be effectively reprojected. I tested a few points between the somerc projection and WGS84 with the PROJ.4 "cs2cs" command and found there was often poor fidelity - likely indicating that points were being transformed that are far outside the well defined area for the projection. I did successfully run your gdalwarp command by adding: --config CHECK_WITH_INVERT_PROJ FALSE on the commandline, but I'm not convinced that the results are actually very accurate or meaningful. I'd suggest you reconsider whether you really want to try and warp nearly the whole world to a swiss oblique mercator projection. Possibly Even could consider improving the error reporting in this case if the issue is really that the transformation is not round tripping well.
