Hey,
I’m already in touch with Ableton on this issue, but I wanted to ask if anyone here has seen this kind of issue:
In Ableton Live 12 specifically (not 11), any calls we make into libfmt functions crashes the DAW immediately with a segfault.
Now, I could just tear out the {fmt} dependency, but I’m really interested in how / why this might occur.
We build fmt ourselves, everything is “vanilla” Apple clang. Has anyone experienced something similar?
Oh, I think I had this.
I was adding fmt as a library. If you change the config so that fmt is only included as a header file then that fixed it for me.
To do that look up the fmt documentation.
As to why the crash happens with the lib version…dunno.
This worked. This ecosystem is insane.
For anyone working with CMake, the solution boils down to removing fmt from your target_link_libraries, and instead adding target_include_directory(fmt/include) and target_sources(fmt/src/format.cc).
