Hi Werner,

I tried to subscribe to the mailling list but https://lists.nongnu.org is currently unreachable.

I've found a bug related to commit #6a92b1fadde26477a9179cbea988b3e04bd2decc.

In ftgzip.c line 749 this code

err = inflateInit2( &stream, MAX_WBITS );

was replaced 

with err = inflateInit2( &stream, MAX_WBITS|32 );

This makes the function call fail as there is this check for the window size in inflate.c: if (w < 8 || w > 15),

with w being  MAX_WBITS|32 = 15|32 = 47 !

I believe this should be fixed as it broke all WOFF font loading in my code.

Best,

Lorcan
