Rare fails of bibtex8 and/or bibtexu test

[Dr. Werner Fink]

Hi,

I face rare and random fails of tests/bibtex8.test and/or tests/bibtexu.test
... e.g. this on an e.g. x86_64, the logs looks like (I've added an ERR trap
to catch this)

No idea what the cause of the empty tests/xexampl.bbl is.  Should I increase
string values of bibtex

 % BibTeX only (max_strings also determines hash_size and hash_prime).
 ent_str_size = 500
 glob_str_size = 200000
 max_strings.bibtex  = 200000
 max_strings.bibtex8 = 200000
 max_strings.bibtexu = 200000
 max_strings.pbibtex = 200000
 max_strings.upbibtex= 200000

at least the stack size is set to unlimited for the full build process.
