examples/ucontext-cp.c: cope with variable SIGSTKSZ
|
||||||
|
|
||||||
|
The size of C arrays at file scope must be constant. The following
|
||||||
|
compiler error occurs with recent upstream glibc (2.33.9000):
|
||||||
|
|
||||||
|
CC ucontext-cp
|
||||||
|
ucontext-cp.c:31:23: error: variably modified ‘stack_buf’ at file scope
|
||||||
|
31 | unsigned char stack_buf[SIGSTKSZ];
|
||||||
|
| ^~~~~~~~~
|
||||||
|
make[1]: *** [Makefile:26: ucontext-cp] Error 1
|
||||||
|
|
||||||
|
The following glibc commit changed SIGSTKSZ from a constant value to a
|
||||||
|
variable:

Allocate the stack buffer explicitly to avoid declaring an array at file
|
||||||
|
scope.
