Summary: A program being executed under callgrind terminates as
soon as using fmt::format() in case of being compiled
as RelWithDebInfo.
Classification: Developer tools
Product: valgrind
Version: 3.22.0
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: callgrind

demo program to reproduce the issue
SUMMARY
A program being executed under callgrind terminates as soon as using
fmt::format() in case of being compiled as RelWithDebInfo.
STEPS TO REPRODUCE
1) unzip the attachment callgrind_demo.zip to ~
2) cd ~/callgrind_demo; rm -rf build/; mkdir build; cd build/; conan install
--profile=../linux_x86_release .. hello-world/0.0.1@siemens-energy/stable;
cmake ..; cmake --build . --verbose; /usr/local/bin/valgrind --tool=callgrind
--callgrind-out-file=callgrind.$RANDOM.log
~/callgrind_demo/build/bin/callgrind_demo
OBSERVED RESULT
The RelWithDebInfo version of "callgrind_demo" program terminates unexpectedly
when being executed under callgrind:

Aborted
EXPECTED RESULT
Successful execution (as well as it is successful for the debug version)
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian GNU/Linux 12 (bookworm) in a WSL
ADDITIONAL INFORMATION
If callgrind_demo is compiled as debug version everything works fine.
The simple program to reproduce the issue can be found in the attachment as
well:
#include <fmt/core.h>
int main() {
auto test = fmt::format("{}", "Hello world.");
return 0;
}
