Nice things about libbacktrace are that the generation of stack traces is
documented to be async signal safe on most platforms (with a #define to figure
that out, and a more minimal safe version always available) and that it
supports a wide range of platforms:
Sadly, it looks like the library is seldom distributed. For example,
Debian seems to only have a package called android-libbacktrace which I
imagine is not what we want. On my system I see a static library only
-- is that enough? That file is part of package libgcc-10-dev, which
tells me that we can't depend on that for packaging purposes.
It would be a pretty big win even if the improved backtrace is only
available in dev environments -- this is what pgBackRest currently does.
We are also considering adding this library to production builds but
have not pulled the trigger on that yet since we are a bit worried about
possible performance impact and have not had time to benchmark.
