From 4078a5c31fa67987051c2180db7a07702534032f Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 8 Nov 2016 18:03:42 -0500 Subject: fix build regression on archs with variable page size commit 31fb174dd295e50f7c5cf18d31fcfd5fe5a063b7 used DEFAULT_GUARD_SIZE from pthread_impl.h in a static initializer, breaking build on archs where its definition, PAGE_SIZE, is not a constant. instead, just define DEFAULT_GUARD_SIZE as 4096, the minimal page size on any arch we support. pthread_create rounds up to whole pages anyway, so defining it to 1 would also work, but a moderately meaningful value is nicer to programs that use pthread_attr_getguardsize on default-initialized attribute objects. --- src/internal/pthread_impl.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/internal/pthread_impl.h b/src/internal/pthread_impl.h index 3890bb56..7a679dbf 100644 --- a/src/internal/pthread_impl.h +++ b/src/internal/pthread_impl.h @@ -143,7 +143,7 @@ void __block_app_sigs(void *); void __restore_sigs(void *); #define DEFAULT_STACK_SIZE 81920 -#define DEFAULT_GUARD_SIZE PAGE_SIZE +#define DEFAULT_GUARD_SIZE 4096 #define __ATTRP_C11_THREAD ((void*)(uintptr_t)-1) -- cgit v1.2.1
