Bug 948356 – dev-libs/userspace-rcu-0.15.0 compile error urcu-bp.c implicit declaration of function assert

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Joe Harvell 2025-01-18 17:13:14 UTC]

Compiling with gcc14 it looks like assert.h is needed but not (transitively included).  See below:

urcu-bp.c: In function 'expand_arena':
urcu-bp.c:412:17: error: implicit declaration of function 'assert' [-Wimplicit-function-declaration]
  412 |                 assert(new_chunk == last_chunk);
      |                 ^~~~~~
urcu-bp.c:42:1: note: 'assert' is defined in header '<assert.h>'; this is probably fixable by adding '#include <assert.h>'
   41 | #include <urcu/urcu-bp.h>
  +++ |+#include <assert.h>
   42 | #define _LGPL_SOURCE
urcu-bp.c:412:17: warning: nested extern declaration of 'assert' [-Wnested-externs]
  412 |                 assert(new_chunk == last_chunk);
