# New Ticket Created by Tom Hukins # Please include the string: [perl #121662] # in the subject line of all future correspondence about this issue. # <URL: https://rt.perl.org/Ticket/Display.html?id=121662 > It's unusual to compile Perl with -DPERL_DISABLE_PMC, but it's something that has worked in previous versions of perl. On blead, tests in t/run/switchM.t fail. The attached patch skips those tests using a crude regular expression: a better approach that I don't know of might exist. Please apply this patch, or something that does the job better, before 5.20 so everyone can continue to compile and use Perl 5 without PMC support. Thanks, TomThread Previous
