[OSRM-talk] Options on compiling: Differences between "Release" and "Debug" Mode Compilation

[Nils Liebelt]

Hi,

I was able to get the version v0.3.4 running without crashes on AWS
EC2 by lowering the gcc optimization profile.
Edit the 'CMakeLists.txt' and add 'set(CMAKE_CXX_FLAGS_RELEASE "-O1")'


Cheers,

Nils
