Bug ID: 475780
Summary: helgrind and drd: undefined symbol for shared library
which calls pthread_mutex_init with attribute
Classification: Developer tools
Product: valgrind
Version: 3.21.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: helgrind
Assignee: jsew...@acm.org
Reporter: piotr.troja...@gmail.com
Target Milestone: ---
Created attachment 162400

Script and code to reproduce the problem
SUMMARY
When the application loads a shared library that calls pthread_mutex_init with
its second parameter "attr" being other than NULL, then helgrind and drd die
with message:
undefined symbol: pthread_mutexattr_gettype
STEPS TO REPRODUCE
1. extract the attached archive and execute ./run.sh
2. this will build the shared library and a program that loads it
3. then it will run the valgrind tools that die
OBSERVED RESULT
./load: symbol lookup error: vgpreload_drd-amd64-linux.so: undefined symbol:
./load: symbol lookup error: vgpreload_helgrind-amd64-linux.so: undefined
symbol: pthread_mutexattr_gettyp
EXPECTED RESULT
The script should only print debug output about activating the shared library
code.
SOFTWARE/OS VERSIONS
Linux: Debian GNU/Linux 11 (bullseye), x86_64
Valgrind Version: 3.21.0 (compiled from source)
ADDITIONAL INFORMATION
I guess the problem is that the interceptors in helgrind/hg_intercepts.c and
drd/drd_pthread_intercepts.c call pthread_mutexattr_gettype, which fails to be
dynamically loaded by the vgpreload_helgrind-amd64-linux.so and
vgpreload_drd-amd64-linux.so libraries.
