Bug ID: 2575
Summary: RE unsafe in static initializers
Product: PCRE
Version: 8.44
Hardware: All
OS: All
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: p...@hermes.cam.ac.uk
Reporter: billy.dona...@gmail.com
CC: pcre-dev@exim.org
ASAN reports an initialization order fiasco when I create an RE to initialize a
static-duration variable, because the static `default_options` variable hasn't
been initialized yet.
In RE::Init, line 106 of pcrecpp.cc, here
https://vcs.pcre.org/pcre/code/trunk/pcrecpp.cc?annotate=1763&pathrev=1763
options_ = default_options;
But default_options was defined on line 82 as a nonlocal static.
static RE_Options default_options;
There are lots of fixes.
One fix might be to bring default_options inside the Init function.
