I did a bisect and found two relevant commits:

1) c312b100: PR target/83712

Before: error: ‘asm’ operand has impossible constraints
After:  internal compiler error: Segmentation fault

2) eaefe34f: PR target/84876

Before: internal compiler error: Segmentation fault
After:  internal compiler error: Maximum number of LRA assignment passes is
achieved (30)
