valgrind log file and sample source code
SUMMARY
When valgrind is used on an application with hdf5, an "unhandled instruction
bytes" error is displayed (cf vg_log.txt)
STEPS TO REPRODUCE
1. compile sample program with hdf5:
g++ -g h5simple.cpp -lhdf5 -o h5s_9.2.0
2. run it with valgrind
valgrind -v --log-file=vg_log.txt ./h5s_9.2.0
OBSERVED RESULT
Valgrind halts execution with "unhandled instruction bytes" message.
EXPECTED RESULT
"Normal" valgrind mem-check operation
SOFTWARE/OS VERSIONS
Linux aim-frog 4.19.66-gentoo #1 SMP Mon Sep 9 09:32:22 -00 2019 x86_64
Intel(R) Xeon(R) W-2195 CPU @ 2.30GHz GenuineIntel GNU/Linux
ADDITIONAL INFORMATION
Outside of valgrind the application runs without errors.
I could reproduce the error with valgrind versions 3.13.0, 3.14.0, 3.15.0.
It is independent of the compiler i used (gcc 6.4.0,7.4.0,8.3.0,9.2.0)
The version of hdf5 is 1.10.5
