Prior to this change
Curl_parsenetrc()would return 27 if thestrdup()ofpwdirfailed even though a) the function is declared to return anintandCURLE_OUT_OF_MEMORYis anenum, and b) the description in the header file is the function "returns -1 on failure, 0 if the host is found, 1 is the host isn't found"The knock on effect is that libcurl would attempt to info "Couldn't find host www.example.com in the .netrc file; using defaults" and continue running rather than erroring with a
CURLE_OUT_OF_MEMORYcode straight away.However, the chances that curl or any application developed with libcurl continuing after a memory allocation failure is very low and would presumably return the correct error code on the next allocation failure.
