Bug #: 53370
Summary: Unbalanced parenthesis when using __attribute__
Classification: Unclassified
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
When using __attribute__((packed(N))), an unbalanced amount of parenthesis can
be used and no compilation error is detected. The documentation states:
"Note that __attribute__ spelled with two underscores before and two after, and
there are always two sets of parentheses surrounding the contents."
So this looks like a bug. To reproduce this error, compile this:
int main() {
__attribute__((aligned(16)) char arr[5];
}
Which contains three '(' and two ')' and still compiles. Note that gcc does
detect this error, g++ does not.
