with OOM debug option: section type conflict with __c (PSTR)

[d-a-v]

Commit 461c922 (#3769) introduces a call to assert() which causes this error when OOM is enabled.

Calls to malloc and assert are done in the same cpp file libraries/ESP8266mDNS/ESP8266mDNS.cpp (by calling seek() from inside UdpContext.h)

cores/esp8266/umm_malloc/umm_malloc_cfg.h:188:40: error: mem_debug_file causes a section type conflict with __c
 #define malloc(s) ({ static const char mem_debug_file[] PROGMEM = __FILE__; malloc_loc(s, mem_debug_file, __LINE__); })

         assert(isValidOffset(pos));

I'm not sure how this can be handled yet.
