8 months ago Hi @Malfoy, that seems very strange indeed. I confirm the warning regarding the strict aliasing rule, but I never saw compilation issues on gcc-11 and gcc-12.
I can successfully compile with all the following versions, both on Linux and Mac OS.
gcc version 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04)
gcc version 11.1.0 (Ubuntu 11.1.0-1ubuntu1~18.04.1)
gcc version 12.3.0 (Ubuntu 12.3.0-1ubuntu1~22.04)
Apple clang version 13.0.0 (clang-1300.0.27.3)Could you please better check or provide the OS name?
It looks like your machine has problems in hashing 128-bit integers. If so, the solution is to explicitly provide the hasher functor to work with __uint128. The problem here is that I cannot test if this approach works on your end because I cannot replicate your issue.

Hello @jermp! I'm trying to build fulgor and I got such compilation problem on several machines using gcc11 and 12
