The bootstrap is finished now: my last one is a week and a half ago, but
at least some of the regressions are wide-int related:

+FAIL: gcc.target/sparc/pdist-2.c (internal compiler error)
+FAIL: gcc.target/sparc/pdist-2.c (test for excess errors)
+UNRESOLVED: gcc.target/sparc/pdist-2.c scan-assembler-not pdist\\t%
+UNRESOLVED: gcc.target/sparc/pdist-2.c scan-tree-dump optimized "return 475"
+FAIL: gcc.target/sparc/pdist-3.c (internal compiler error)
+FAIL: gcc.target/sparc/pdist-3.c (test for excess errors)
+WARNING: gcc.target/sparc/pdist-3.c compilation failed to produce executable
+FAIL: gcc.target/sparc/pdistn-2.c (internal compiler error)
+FAIL: gcc.target/sparc/pdistn-2.c (test for excess errors)
+UNRESOLVED: gcc.target/sparc/pdistn-2.c scan-assembler-not pdistn\\t%
+UNRESOLVED: gcc.target/sparc/pdistn-2.c scan-tree-dump optimized "return 473"

The first is:

Most likely unrelated, PR libfortran/52539

Can't tell, but failure is consistent.
