Bug ID: 416286
Summary: DRD reports “conflicting load” error on
std::mutex::lock
Product: valgrind
Version: 3.15 SVN
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: drd
Assignee: bvanass...@acm.org
Reporter: igor.chorazew...@intel.com
Target Milestone: ---
Created attachment 125144
--> https://bugs.kde.org/attachment.cgi?id=125144&action=edit
test code
When I run attached code under drd I get "conflicting load" error on
std::mutex::lock. Both removing 'counter' constructor and calling 'get_counter'
in main thread before any thread starts solves the issue. It seems drd thinks
that static initialization of an object is not thread safe.
I tested this with g++-9.2.1 and clang++ 9.0.0.
