Unfortunately, it is not a compile-time check... I mean smth like https://github.com/openssl/openssl/blob/ab5c77b4766e0992751d86560193ca42b49cf316/include/openssl/e_os2.h#L198-L202 but not sure it is applicable to external functions... On Thu, Nov 21, 2019 at 1:42 PM Salz, Rich wrote: > >-

Adding a compile time check would be good. I’m not sure how. It would be possible to implement a malloc failure feature in the test suite that systematically runs a test many times, failing successive malloc calls. I’m kind of surprised that the various static analysers hadn't found some of

Hello, Observing a series of similar bugs related to a lack of checks of the malloc return values, I wonder if we could automate the search of these errors on the compile level (e.g. similar to the __owur macro)? -- SY, Dmitry Belyavsky
