Change the stack overflow test to 128kb stacksize
|
||
|
|
|
||
|
|
on ppc64 fedora, the thread_pool_stack minimum is 128kb due to
|
||
|
|
sysconf(_SC_THREAD_STACK_MIN) = 131072
|
||
|
|
|
||
|
|
It does not harm the test to use a larger stacksize, so we adjust it to
|
||
|
|
this requirement for consistency and simplicity
