According to Espressif's SSL user manual, using SSL requires quite a large amount of RAM. Is your program already using a lot of RAM?
If you have e.g. large string literals, you could try moving them to the flash memory by using the ICACHE_RODATA_ATTR as described in the FAQ. Also, move your own functions (except probably interrupt handlers and other critical ones) to the flash by using the ICACHE_FLASH_ATTR.

I found that this httpclient uses strlen instead of os_strlen and also own implementation of atoi could save some bytes.

One can also link against -lcirom instead of -lc, it puts all stdlib functions to irom.
