In the case of current esp8266 port, heap is inside BSS, so scanning it picked up a lot of dead pointers. esp8266: Fix garbage collector by hard-coding stack end address. 2015-05-06T13:01:07+00:00 Josef Gajdusek atx@atx.name 2015-05-06T12:34:32+00:00 urn:sha1:28076f3d4b3bf58aa86d6346af88665f7e5c6031 As user_init() is not a true main functions, the stack pointer captured within is not pointing at the base of the stack. This caused gc_collect being called with sp being higher than stack_end, causing integer overflow and crashing as gc tried to scan almost the entire address space. esp8266: Prefix includes with py/; remove need for -I../py. 2015-01-01T21:16:58+00:00 Damien George damien.p.george@gmail.com 2015-01-01T21:16:58+00:00 urn:sha1:fe7d542352738e14c6d03bcc55b1e89b4e7c5c96 esp8266: New port of Micro Python to ESP8266 wifi module. 2014-11-27T20:30:33+00:00 Damien George damien.p.george@gmail.com 2014-11-27T20:30:33+00:00 urn:sha1:075d597464be619475535930de2f36abe69176f8
