Congrats on your investigation work; I wish I could shed more light on
what this workaround was meant to accomplish.  I've tried to reproduce
my original issue, but so far I was not successful.

If my initial report can be trusted, the bug happened (1) back when the
development branch was 27.0.50 (commit 61fb521481) (2) on an old
battered laptop that I can no longer power on without disturbing loud
fan demons.

26.3 no longer compiles on my end[1], so all I could do was try to
reproduce on master, where the workaround has been reverted, on other
computers I have lying around.  The symptoms have not resurfaced yet,
so… I'll go with a timid, yet hopeful "yay" 🙂

sysdep.c:1795:22: error: variably modified ‘sigsegv_stack’ at file scope
