Crashes on iOS devices in some cases

[sindresorhus]

I'm not able to reproduce myself, but I'm seeing it in Sentry for my app using Whisper.cpp 1.5.0 from Swift.

EXC_BAD_ACCESS: backend > de=3 "Encountered un > decoder.blocks. > Error Domain=AGXMetalA12 Code=3 "Encountered unlowered function call to air.simd_max.f32" UserInfo={NSLocalizedDescription=Encountered unlowered function call to air.simd_max.f32} > ggml_metal_init >

Seems to be a pretty widespread issue. Already seeing 100+ users having this crash in Sentry.
