Fix some possible low-memory failures in regexp compilation. newnfa() failed to set the regex error state when malloc() fails. Several places in regcomp.c failed to check for an error after calling subre(). Each of these mistakes could lead to null-pointer-dereference crashes in memory-starved backends.
