#18101 new defect

perl from BB 14.07 cannot use negative array indexes

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Barrier Breaker 14.07
Keywords: perl array index Cc: naoir@…


perl from BB 14.07 package repository is broken as it cannot use negative array indexes. Because of this cannot find object modules.

#!/usr/bin/perl -w

@data = ("element0");
print "$#data\n";
print "$data[0]\n";
print "$data[-1]\n";

Use of uninitialized value $data[255] in concatenation (.) or string at ./ line 6.

This is with openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs.
Same source for perl 5.20.0 works fine when compiled for my linux.

Thanks for your report.

Looks much like the same problem ARM had a while ago to me(fixed in a199373, for reference). The attached patch should fix the problem. Can you confirm that?

Yes, with the patch applied the new perl binary works fine with negative array indices. Great job. Thanks.
