The problem is curl depends on USERPROFILE and APPDATA environment variables and when both are unset it quickly fails with curl: (27) Out of memory.
Points to address:
- is curl expected to fail when the env vars are missing?
- should it fail with out of memory error despite of this seems more like configuration/context/file access problem?
- the error does not occur when I run
curl --versionor e.g.curl --help - issue curl error: out of memory (27) #3117 has exactly the same symptoms
- difficult to debug as the error is misleading and afaik this dependency is not documented
The solution is
- to set one of the variables or both to its appropriate value
- to make sure curl is invoked with all environment variables
Feel free to close.
