Bug ID: 96485
Summary: Lambda parsing regression in GCCs 9 and onwards
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: s_gccbugzilla at nedprod dot com
Target Milestone: ---
As the repro at https://godbolt.org/z/Gvx75e shows, the following code compiled
fine in GCCs up to and including GCC 8.3:
```
void test()
{
[]()
#if 1
__attribute__((no_sanitize_undefined))
#endif
->int {
return 0;
};
}
```
>From GCC 9 onwards, we get:
```
<source>: In lambda function:
<source>:7:5: error: expected '{' before '->' token
7 | ->int {
| ^~
<source>: In function 'void test()':
<source>:7:5: error: base operand of '->' has non-pointer type
'test()::<lambda()>'
<source>:7:7: error: expected unqualified-id before 'int'
7 | ->int {
| ^~~
Compiler returned: 1
```
This code compiles fine in clang, incidentally, though it doesn't recognise the
attribute.
