syntax error on valid function try-catch block

[Martin]

Hi,

the latest cppcheck exits with a syntax error on this valid code:

int main(int argc, char **argv) try
{
return 0;
}
catch (Error &e)
{
return 1;
}

error: syntax error: keyword 'try' is not allowed in global scope [syntaxError]
int main(int argc, char **argv) try

See f.e.: https://stackoverflow.com/questions/8405390/function-try-catch-syntax-and-main
Could you please check?

Thanks,
Martin

Sorry, already seems to handled by:

A stylistic question. Why not add extra semicolons to make it more readable?

[Daniel Marjamäki]

I don't think I've ever seen such syntax in real code. Is this from real production code?

[Martin]

Yes, we have examples of that in our production code, and it's a valid C++ construct:

[Daniel Marjamäki]

Yes it is valid. Cppcheck should handle it. I think it looks weird but feel free to use whatever constructs you like in your code. If you have time to fix this in Cppcheck, feel free to do it. I would add a pass in our tokenizer that inserts extra { and } tokens, that should be relatively simple and quick.

Hi,

Is there any workaround regarding this issue?
The error code is syntaxError, can I suppress syntaxError using the command line parameters?

syntaxError is handled by the compiler so I think it's OK to suppress it until it will be fixed in cppcheck.

[Daniel Marjamäki]

to suppress it:

danielm@debian:~/cppcheck$ ./cppcheck 9728.cpp 
Checking 9728.cpp ...
9728.cpp:2:1: error: syntax error: keyword 'try' is not allowed in global scope [syntaxError]
try {} catch (...) {}
^
danielm@debian:~/cppcheck$ ./cppcheck --suppress=syntaxError 9728.cpp
