floating point exception 8 when running make

[Valery Tolkov]

Hi, all!

Gnu make suddenly stopped working about half an hour ago with the error below. It was working just fine earlier today without any changes in makefile or invocation.

Exact target file doesn't matter, all files give the same error. If I do a clean build without any existing targets, it works. But second time it fails again.

...

Must remake target `bin/dbg/clr/clr.o'.

clang++ --config ./warnings.cfg -g -O0 -DDEBUG -std=c++2a -fmodules  -I . -I vt -D HAVE_STDDEF_H -D HAVE_STDINT_H -D HAVE_SYS_TYPES_H -D OSX -D UNIT_TESTS -c clr/clr.cc -o bin/dbg/clr/clr.o

Putting child 0x600001b94230 (bin/dbg/clr/clr.o) PID 35065 on the chain.

Live child 0x600001b94230 (bin/dbg/clr/clr.o) PID 35065 

Reaping losing child 0x600001b94230 PID 35065 

make: *** [bin/dbg/clr/clr.o] Floating point exception: 8

Removing child 0x600001b94230 PID 35065 from chain.

The error appears on both:

GNU Make 4.3

Built for x86_64-apple-darwin21.1.0

and:

GNU Make 3.81

This program built for i386-apple-darwin11.3.0

Thanks,
