Still needs to be documented, somehow/somewhere. The env var OPENSSL_MALLOC_FAILURES controls how often malloc/realloc should fail. It's a set of fields separated by semicolons. Each field is a count and optional percentage (separated by @) which defaults to 100. If count is zero then it lasts "forever." For example: 100;@25 means the first 100 allocations pass, then the rest have a 25% chance of failing until the program exits or crashes. If env var OPENSSL_MALLOC_FD parses as a positive integer, a record of all malloc "shouldfail" tests is written to that file descriptor. If a malloc will fail, and OPENSSL_NO_CRYPTO_MDEBUG_BACKTRACE is not set (platform specific), then a backtrace will be written to the descriptor when a malloc fails. This can be useful because a malloc may fail but not be checked, and problems will only occur later.
