Bug#929777: gcc-6: output errors to .gcda file are not checked
Package: gcc-6
Version: 6.3.0-18+deb9u1
Severity: normal
When executing a program compiled with profile generation
(-fprofile-generate), the obtained .gcda file is sometimes
empty (apparently due to write errors). The problem is that
the program terminates successfully, so that the issue is
not detected. Well, "gcc -fprofile-use" outputs a warning,
but that's all.
Write failures should be detected, and when this happens,
the program should terminate with a non-zero exit status
as usual.
