I think you're exceeding a Perl limit on the length of function
names.  From perldiag:

  Identifier too long
    (F) Perl limits identifiers (names for variables,
    functions, etc.) to about 250 characters for simple
    names, and somewhat more for compound names (like
    `$A::B').  You've exceeded Perl's limits.  Future verĀ­
    sions of Perl are likely to eliminate these arbitrary
    limitations.

files_apache_group_apache_htdocs_nwa_integration_html_validate_login_aspx685
3b58099f6e95af8bde3b47da84726

which is 257 characters.  I just tried to define it in a test
script and received the same identifier too long error.

Joshua will likely want a better fix that preserves as
much of the path info as possible, but you can try this
simple patch against 2.31 that shortens the function name
and see if it solves the problem:
