Hi Eric, So looking at it again, this seems to be happening during stage3.
And there aren't any special flags being set.

What's a little strange is that there is a .cold part in the backtrace: #14 0x015fd511 in uw_init_context_1.cold () at ../../../gcc-8-20181214/libgcc/unwind-dw2.c:1386 and this shouldn't happen for the compiler built during stage #1. Do you add -O2 to the STAGE1_CFLAGS or some such? If so, can you lower it to -O1 or -O0? -- Eric Botcazou
