Scary, they broke it. The debian manpage is explicit though: if size is equal to zero, and ptr is not NULL, then the call is equivalent to free(ptr) > http://lists.gnu.org/archive/html/bug-gnulib/2011-03/msg00243.html . So it seems eglibc has broken it, and not glibc, at leats according tot he glibc bug report, which strongly indicates that this is a defetc in the standard (and it likely is, as the overwhelming behaviour on unices is for relaloc to free). > IMHO, in a world with that kind of mess going on, the new "safe" > behavior for portable code may just be to never use realloc(p,0) > because you can't trust what it means :( Well, the code in libev isn't portable, it is glibc specific, and glibc guarantees the correct behaviour. It is clearly a bug in glibc that needs to be resolved. While libev can (and should) work around this bug, this doesn't help any of the other programs who rely on correct behaviour. It cannot be fixed in libev. -- The choice of a Deliantra, the free code+content MORPG -----==- _GNU_ http://www.deliantra.net ----==-- _ generation ---==---(_)__ __ ____ __ Marc Lehmann --==---/ / _ \/ // /\ \/ / schm...@schmorp.de -=====/_/_//_/\_,_/ /_/\_\ _______________________________________________ libev mailing list libev@lists.schmorp.de http://lists.schmorp.de/cgi-bin/mailman/listinfo/libev
