The fixes in curl#10079 brought a (seemingly unrelated) change of open mode from `wb`/`ab` to `wb+`/`ab+` for the headerfile. This makes it no longer possible to write the header file to e.g. a pipe, like: curl -D >(grep ...) file:///dev/null Which presently results in `Warning: Failed to open /dev/fd/63` See curl#10079 Closes curl#10675
