Bug#900829: perl/experimental: FTBFS on hppa: t/re/regexp_qr_embed_thr.t failure

[Niko Tyni]

Source: perl
Version: 5.28.0~rc1-1
X-Debbugs-Cc: debian-hppa at lists.debian.org

This package failed to build on hppa (only).

 https://buildd.debian.org/status/fetch.php?pkg=perl&arch=hppa&ver=5.28.0%7Erc1-1&stamp=1528117759

 t/re/regexp_qr_embed_thr ....................................... free(): invalid pointer
 FAILED--no leader found

Copying the debian-hppa list. Could somebody please investigate?
If it's a Perl regression from 5.26, I'm sure upstream would be
interested in fixing it before the 5.28.0 release.
