Re: [Gc] Strange leak in simple code

Garbage is defined as unreachable objects.
All of your objects are reachable by following
the next chain.  If you added some code like
this in the loop

if( i++ % 1024 == 0 ) list = NULL;

then only the last bunch would be accessible
and all previous would be garbage and collected.

Subject: [Gc] Strange leak in simple code

Using libgc from Ubuntu 15.04 (7.2b-6.4) this simple code leaks: 

#include <gc.h> struct list { struct list * next ; }; int main () { GC_INIT (); struct list * last = NULL ; for (;;) { struct list * nuo = GC_MALLOC ( sizeof ( struct list )); nuo -> next = NULL ; // if next line is commented, then no leakage if ( last ) last -> next = nuo ; last = nuo ; } }
