Note that it is calling paramVal::getInteger in a try/catch block that explicitly catches the exception you are getting, ParamValNotDefined. So I don't understand why this is causing your program to terminate, rather than simply catching the error and return and error status.
It seems like perhaps there is something different about the way C++ exception handling works with the linux-arm architecture? No one has ever reported this error before, but most people are using linux-x86_64.
Just poking...
Inside the ARM toolchain doc [1] I found thatThe ARM compilation tools fully support C++ exception handling. However, the compiler does not support this by default. You must enable C++ exception handling with the --exceptions option.Far too obvious to be the cause, is it?
I don't think that it would be, because any reasonable Linux ARM system would be using GNU (or Clang) compilers, not the ARM compiler suite. "--exceptions" doesn't look like a GCC option either, and Linux userspace as a whole would be broken if built with "-fno-exceptions".
