...Insider build) probably soon after unwinding the stack, but only with GCC 10 / MinGW 7 and only in one of the no-segfault tests, and only with -03 (not -O2, not with with -O3 -fno-split-loops). The problem was sensitive to these optimization options interestingly on the call site of long jump (do_abs), even when it was not an immediate caller of the longjump. I've not tracked this down yet, it will require looking at the assembly level, and I was suspecting a compiler error causing the compiler to generate code that messes with the stack or registers in a way that impacts the upcoming...
