Subject: tests: run-backtrace-demangle.sh check exitcode and max number of frames.
X-Git-Tag: elfutils-0.159~55
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d7cffa77ae9eb28a682e436251ab79e86b4e4f64;p=thirdparty%2Felfutils.git

tests: run-backtrace-demangle.sh check exitcode and max number of frames.

There can be more than 3 frames, but depending on the system/installed
glibc we might not be able to unwind fully till the end.
cxxfunc -> f -> main
Expect to see the top two and a warning that there are more frames
(exit code 1)
