Is it a bad idea to activate lens-corrections in camera, when also use lens-correction in Lightroom?

Question

My EOS has the option to correct known lens-aberration which is activated at the moment.I use Lightroom (5.2) for post-processing, which can also correct lens-aberration.Is it a problem to activate both cam- and Lightroom-correction or is the Lightroom-correction smart enough to recognize that there is nothing (or not so much) too to anymore?Mainly I use raw-format and seldom (but not never) jpeg. I suppose raw doesn’t safe the cam-correction info, so I guess my question is only relevant for jpeg, isn´t it?**Update EXIF:**I was looking to the EXIF und IPTC informations in Lightroom, but no attribute tells me that the cam correct lens-aberrations.**Update Test:**I do a simple test. Post results as a separate answer for better discussion.

Answer 1

It should not affect the performance of LR's capability to perform Lens Correction of the image uploaded, even if it was already corrected in-camera, because LR will scan the image as it is. You can usually tell from the way the photo looks, if it needs more adjusting. It will either be bulging from distortion or sinking into the frame. Also check your vertical and horizontal lines to see if they're straight, and that can be helpful as well.
