During the merge, the redundant assignment was not removed. (since collected is a local variable and no pointers to it escape, it doesn't seem possible for the placement of the assignment before or after GC_ENTER() is important) This diagnostic was found by clang 7's scan-build static analyzer. Include display objects in gc. 2019-06-06T21:49:32+00:00 Dan Halbert halbert@halwitz.org 2019-06-06T21:49:32+00:00 urn:sha1:62de2506e47c14a71c7a9fe04360697ccb966aeb Correct collect of permanent pointers. 2019-04-18T22:44:44+00:00 Scott Shawcroft scott@tannewt.org 2019-04-18T22:44:44+00:00 urn:sha1:54ef87c6de483fdd062dabf0d560ecabd73aef94 The previous implementation managed to keep all but the head pointer of the list. Fixes #1814 Check that a never free pointer is on the heap. 2019-04-09T22:12:28+00:00 Scott Shawcroft scott@tannewt.org 2019-04-09T22:12:28+00:00 urn:sha1:ee7a77db65f24b3e34a9b9b733887cab3434d225 This fixes a crash on boards with built-in displays which statically allocate the display bus. When the pointer is provided to never free, it tries to allocate on the non-existant heap and crashes. Reorganize board busses into shared-bindings and shared-module. 2019-04-08T23:58:50+00:00 Scott Shawcroft scott@tannewt.org 2019-04-08T23:58:50+00:00 urn:sha1:0f003ac5b8312fafb120e86e05eefd2431014d8c Fix function signature 2019-03-12T21:05:31+00:00 Scott Shawcroft scott@tannewt.org 2019-03-12T21:05:31+00:00 urn:sha1:911509c80c0767bed81a4a3757c7691af9be19ea
