My YAML being read is 
---
NODE:
  match: !!perl/regexp (?^ui:OK\ Server\ Connection\ 1\.001)

[download]
After loading/dumping it looks like this 
---
NODE:
  match: !!perl/regexp (?^u:(?^ui:OK\ Server\ Connection\ 1\.001))

[download]
After 20 load/dump cycles it looks like this: 
---
NODE:
  match: !!perl/regexp (?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?
+^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^u:(?^ui:OK\
    Server\ Connection\ 1\.001)))))))))))))))))))))

My test: 
perl -MYAML::XS -E 'my $y=YAML::XS::Load(q{---\nNODE:\n  match: !!perl
+/regexp (?i-xsm:OK\ Server\ Connection\ 1\.001)}); for(1..20) { $y=Lo
+ad(Dump($y)) }; say Dump($y)'

[download]
$YAML::XS::VERSION = 0.66
perl v5.24.3

If I let it run long enough, eventually the parser breaks down. Does anyone have any suggestions?
