Change in 6c44a3a9a8 to line 95 of src/pmc/stringhandle.pmc is likely 
suspect:

         data_struct->record_separator = CONST_STRING(interp, '\n');

In tools/build/c2str.pl, if $_ does not contain a pair of double quotes 
when this regex is reached at line 151:

         my ($str) = m/^\s*"((?:\\"|[^"])*)"/;

... then nothing will be captured and $str will be undefined.

Thank you very much.
