I think it's really dependent of the domain you are working in. Some stuff is better tested than others. In my 5 years careers I found bugs (found and confirmed by compiler authors) in gfortran, xlf and pgfortran. So yes bugs in compilers are rare but sometimes you just keep running into them.

those are quite niche languages though, most people use compilers which are much more widely used.

Clang support for AVX-512 intrinsics is pretty broken
