- Reply-to: gcc-bugzilla at gcc dot gnu dot org
The following invalid code snippet causes an ICE since GCC 3.4.0:
===============================================
struct A {} __attribute__((aligned(;)));
===============================================
bug.cc:1: error: expected primary-expression before ';' token
bug.cc:1: error: expected `)' before ';' token
bug.cc:1: error: expected `)' before ';' token
bug.cc:1: internal compiler error: tree check: expected tree_list, have
error_mark in handle_aligned_attribute, at c-common.c:4698
Please submit a full bug report, [etc.]
This happens more or less with all attributes that take an argument list
and seems to be C++ specific.
Testing a patch.
