>Description:
A mistake by a developer led to some code being on the same line as an #endif conditional.
gcc rightly ignored this line of code, but despite our warning levels did not shout at us. This was a problem as the code being ignored released a lock. When we found the problem we investigated what level would be needed to get a warning and found...
leo:~/deleteme:22$ gcc -Wall yabt.c -o yabt
leo:~/deleteme:23$ gcc -Wall -ansi yabt.c -o yabt
leo:~/deleteme:24$ gcc -Wall -ansi -pedantic yabt.c -o yabt
yabt.c:9: warning: text following `#endif' violates ANSI standard
yabt.c:13: warning: text following `#endif' violates ANSI standard
It seems there is no warning level lower than pedantic to show this, it would be nice if there were.
Attached sample (erroneous) C code to demonstrate problem.
The code that had the bug in has ...
-Wall -Wno-unused -Wno-switch Wpointer-arith -Wredundant-decls -Wnested-externs -Winline -W -Werror
turned on.
>How-To-Repeat:
Compile yabt.c with various warnings.
Only get warned of ignored code with -pedantic
