I was running the tests under tp/t under valgrind and it was mostly fine, apart from an error that came from running
perl -w t/info_tests.t chinese_mixed_with_en_EUC_CN This logs an error with ==400562== Invalid read of size 8 ==400562== at 0x40286C0: strncmp (strcmp.S:170) ==400562== by 0x400668D: is_dst (dl-load.c:216) ==400562== by 0x400810E: _dl_dst_count (dl-load.c:253) ==400562== by 0x400810E: expand_dynamic_string_token (dl-load.c:395) ==400562== by 0x40082B7: fillin_rpath.isra.0 (dl-load.c:483) ==400562== by 0x4008602: decompose_rpath (dl-load.c:654) ==400562== by 0x400ABF5: cache_rpath (dl-load.c:696) ==400562== by 0x400ABF5: cache_rpath (dl-load.c:677) ==400562== by 0x400ABF5: _dl_map_object (dl-load.c:2165) ==400562== by 0x4003494: openaux (dl-deps.c:64) ==400562== by 0x4ACCC27: _dl_catch_exception (dl-error-skeleton.c:208) ==400562== by 0x4003C7B: _dl_map_object_deps (dl-deps.c:248) ==400562== by 0x400EA0E: dl_open_worker_begin (dl-open.c:592) ==400562== by 0x4ACCC27: _dl_catch_exception (dl-error-skeleton.c:208) ==400562== by 0x400DF99: dl_open_worker (dl-open.c:782) ==400562== Address 0x9307ed1 is 1 bytes inside a block of size 8 alloc'd ==400562== at 0x4848899: malloc (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so) ==400562== by 0x40271FF: malloc (rtld-malloc.h:56) ==400562== by 0x40271FF: strdup (strdup.c:42) ==400562== by 0x4008594: decompose_rpath (dl-load.c:629) ==400562== by 0x400ABF5: cache_rpath (dl-load.c:696) ==400562== by 0x400ABF5: cache_rpath (dl-load.c:677) ==400562== by 0x400ABF5: _dl_map_object (dl-load.c:2165) ==400562== by 0x4003494: openaux (dl-deps.c:64) ==400562== by 0x4ACCC27: _dl_catch_exception (dl-error-skeleton.c:208) ==400562== by 0x4003C7B: _dl_map_object_deps (dl-deps.c:248) ==400562== by 0x400EA0E: dl_open_worker_begin (dl-open.c:592) ==400562== by 0x4ACCC27: _dl_catch_exception (dl-error-skeleton.c:208) ==400562== by 0x400DF99: dl_open_worker (dl-open.c:782) ==400562== by 0x4ACCC27: _dl_catch_exception (dl-error-skeleton.c:208) ==400562== by 0x400E34D: _dl_open (dl-open.c:883) There are similar errors for "perl -w t/formats_encodings.t". Running valgrind --vgdb-error=1 perl -w t/info_tests.t chinese_mixed_with_en_EUC_CN" and attaching with gdb, looking at the backtrace, the error arises via a call from iconv_open which is called from get_encoding_conversion in main/utils.c. The address referred to here: ==400562== Address 0x9307ed1 is 1 bytes inside a block of size 8 alloc'd points to the string "ORIGIN" which would be 7 bytes including a final null. One byte before refers to "$ORIGIN". I found a similar report at https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/2015216 Apparently it is due to a bug in valgrind that has since been fixed: https://bugs.kde.org/show_bug.cgi?id=434764 https://sourceware.org/git/gitweb.cgi?p=valgrind.git;h=947388eb043ea1c44b37df94046e1eee790ad776 I will try to add something to the suppressions file.
