Here's another good reason from a C++ compiler error: error : string literal of length 186851 exceeds maximum length 65536 that C++ compilers are required to support [- Werror,-pedantic,-Woverlength-strings]
I get this using a non-gcc compiler on the code generated for the hyperelasticity demo. The error is cause by the repr string which is too long.
