--- Comment #9 from Bruno Haible <bruno at clisp dot org> ---
We now have a generic workaround to this bug:
If the bug occurs in a function foo:
1. Rename foo to foo_internal, mark it as '__attribute__ ((__noinline__))
static' and add a 'char stack_buf[1024]' parameter.
2. In the function foo_internal, drop the stack-allocated buffer and use the
new parameter instead.
3. Create a new function foo, with the same signature as before, that merely
allocates a 'char stack_buf[1024]' on the stack and passes it to foo_internal.
For an example, see
