The behavior is that guild compile 38486-1.scm hangs

These optimization flags eliminate that behavior: the code compiles quickly:
  -O0
  -O1
  -Ono-simplify
  -Ono-contify
  -Ono-cse
  -Ono-specialize-numbers

These optimization flags are ineffective: the behavior remains:
  -Ono-partial-eval
  -Ono-eliminate-dead-code
  -Ono-prune-top-level-scopes
  -Ono-inline-constructors
  -Ono-specialize-primcalls
  -Ono-elide-values
  -Ono-prune-bailouts
  -Ono-peel-loops
  -Ono-type-fold
  -Ono-resolve-self-references
  -Ono-licm
  -Ono-rotate-loops
  -Ono-precolor-calls
