Hello Maxim, thank you very much for indicating the article on Apple Developer. I am final user of Fortran as a physicist who developed some research software just in Fortran. The hardware based on Intel CPU i7 is about nine-years-old, so that I bought a new iMac M3. The new software Sonoma, now Sequoia, according to the article have an architecture that is responsible for the signaled failure.
It is a pity that, attempting to work around the difficulty on Fortran changing gcc port, I found all gcc's branded as notoriously not working, with the (apparent!) exception of gcc14. As a naive user, I now think that problems with Fortran could be overcome with appropriate patches to the linker. But, according to article, the problem is rather old… Otherwise inconvenient is the building procedure of gcc and its library: for around an hour the cpu cores temperature is 100-108 Kelvin, on account that no fan is present in iMac ... Thank you, best wishes, Paolo
