Bug ID: 80380
Summary: misleading behavior with designated initializers for
std::vector
Product: gcc
Version: 6.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ethan at atdllc dot com
Target Milestone: ---
Created attachment 41164

short example (not pre-processed)
Designated initializers are silently ignored when used in a initializer list
for a std::vector.
const std::vector<const char *>strings = {
[ 0] = "zero",
[ 1] = "one",
[20] = "twenty",
};
This compiles silently, and results in a vector with three elements.
Using a std::array does result in an error (error: ‘[0] =’ used in a GNU-style
...), as does initializing an array of char * (sorry, unimplemented:
non-trivial designated initializers not supported).
If someone really wants a preprocessed .ii file, I can add one tuesday.
