#80 0x0115ee6e in main (argc=14, argv=0xa445f8) at emacs.c:2095 Hi Eli, this really look like a libgccjit bug. I think would be interesting if you have time to: 1- produce a libgccjit reproducer (applying the attached patch before running the test) and post it so we can check if we can reproduce and investigate this on other setups. 2- run all the comp-tests.el tests excluding `comp-tests-bootstrap' just to make sure we are fine with all the reduced testcases. Thanks! Andrea
