Package: valgrind
Version: 1:3.1.0-2
Severity: normal
Hi,
The following simple test:
#include <stdlib.h>
int main() { return rpmatch( "leaks" ); }
Produces the output attached below. Looking at the source of
glibc-2.3.2.ds1, stdlib/rpmatch.c -- the 'leak' appears to be
the result of static allocations that are expected to survive
'cached' until the process exits.
It is surely not more of a 'bug' in glibc than anywhere else
that sort of thing is done, and is in fact probably a Good
Thing, so I guess we just need to add the relevant suppressions
for Debian glibc.
I haven't looked at the 2.3.5-11 source (which is the libc
version I'm really using), or updated to 2.3.5-12 which is
in sid now -- but I don't expect this should have radically
changed in either of them.
cheers,
Ron
