I'm glad you raised that point, because I had forgotten it: the  
instructions refer to:

#Flags to build optimized relese version
CXX_OPTFLAGS = O1
C_OPTFLAGS = O1

in GDALmake.opt, but for the life of me, I couldn't find those  
variables set anywhere in that file. (Perhaps I should reiterate that  
I am using the GDAL trunk source, not the stable version that is  
recommended by the imageio-ext instructions.) Perhaps I should have  
set them anew?

Ah-- now we find the worst problem-- I haven't subscribed to that  
list, so I'm less informed than I should be. {grin} I'll rectify that  
mistake promptly.

Thank you so much! I hope I'll be able to contribute something useful  
towards this issue with LizardTech SDK 7.

Meanwhile, hopefully this conversation will have informed the  
geoserver users to stick with LizardTech SDK 6 for now. {grin}
