Subject: [PATCH 3/6] Better handling for realpath() failures in
|
|
windows_make_so() on Cygwin
|
|
|
|
Fix a memory leak which would occur in the case when the result of realpath() is
|
|
greater than or equal to SO_NAME_MAX_PATH_SIZE.
|
|
|
|
Distinguish between realpath() failing (returning NULL), and returning a path
|
|
longer than SO_NAME_MAX_PATH_SIZE
|
|
|
|
Warn rather than stopping with an error in those cases.
|
|
|
|
Original patch from Tim Chick. Memory leak fix by Corinna Vinschen.
