Subject: [Bug c++/102918] New: Undefined behaviour in regex header (uininitialized boolean)
Date: Sun, 24 Oct 2021 21:39:03 +0000 [thread overview]
Message-ID: <bug-102918-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102918
Bug ID: 102918
Summary: Undefined behaviour in regex header (uininitialized
boolean)
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: camilotalero96 at hotmail dot com
Target Milestone: ---
I am using undefined behaviour sanitizers and they are detecting a potential
bug in teh regex header, the specific report is:
`/usr/include/c++/11/bits/regex.h:909:15: runtime error: load of value 192,
which is not a valid value for type 'bool'`
Which does seem like the use of a potentially uninitialized boolean.
