ckitagawa 8614a30bc9 [subset] Fix sbix fuzz problem 2020-01-22 10:11:15 -08:00
ariza 72cbfb9059 remove empty lookup subtables
Added a variant of subset_offset_array which takes an extra arg passed to serialize_subset for this impl.
Added a new api test "test-subset-gpos" for this.

Ebrahim Byagowi a32ecc15ae
Fix collect lookups logic of FeatureVariationRecord
As "Offset to a feature table substitution table, from beginning of the FeatureVariations table."
from https://docs.microsoft.com/en-us/typography/opentype/spec/chapter2 the record should
match its sanitize logic not the reverse way.

Fixes https://crbug.com/oss-fuzz/20021 and https://crbug.com/oss-fuzz/20022

Use REPLACEME tag
So we can use the version we like when we decide what it should be while the next release
and can review the API before the release one other time.

[subset/hvar] minor
not super excited about state of the code around, assuming was needed
so let's add this may unlikely check also.

Fail serialize when map has incorrect value
fixes https://crbug.com/oss-fuzz/19956

am not super happy with the fix, guess we should do some check
before the memcpy anyway as @blueshade7 thinks also,
so let's have it or revert it when we have a better approach for the case.

Remove _POSIX_C_SOURCE definition from the project
Added fpr suncc support but apparently is causing more issues
even on suncc so let's see if we can go without it.
