Boost interprocess segfaults

[Mathias Creutz <mathiascreutz@…>]

Having a boost::unordered map in shared memory and after creation opening it in open_only or open_read_only behaves differently depending on the key length. open_only always works, open_read_only only works if key length is less than 24 bytes.

I've got very simple example code that I'll attach, maybe I am doing something wrong here.

For testing the different behaviour open_only vs open_read_only

[Robert Ayrapetyan <robert.ayrapetyan@…>]

Looks like an expected behavior. When string length is small (less then capacity()), no allocations are required, all characters are stored "in place". Otherwise alloc in "segment" is required (which fails when you open it in "read only" mode). I would suggest to close this ticket as "invalid".
