Here's the backtrace on ia64 (merulo.d.o):
zsh: segmentation fault (core dumped) PERL_DL_NONLAZY=1 perl -Iblib/lib

Core was generated by `perl -Iblib/lib -Iblib/arch t/map8.t'.
Program terminated with signal 11, Segmentation fault.

Looks like the problem is that sizeof(STRLEN) != sizeof(int) but
the map8_recode8() call on Map8.xs:358 mixes up pointers to them.
Also, there seems to be a typo in the function prototype in map8.h so
we don't even get a compiler warning. With that fixed, I see
Map8.xs: In function ‘XS_Unicode__Map8_recode8’:
Map8.xs:358: warning: passing argument 6 of ‘map8_recode8’ from incompatible
pointer type
map8.h:83: note: expected ‘int *’ but argument is of type ‘STRLEN *’
I'm attaching a patch that makes the test pass for me on ia64.
FWIW, this is also [rt.cpan.org #43404] (which contains an identical
patch to mine) and [rt.cpan.org #24652].
It has also failed on amd64 for at least Fedora, see
