Hi, Mohsen,
Thank you for the bug reports. If you are able to open JIRA issues,
please do so (one for each problem below) -- that way you can track
what is happening with them and will be notified via email when they
are fixed.
More comments inline below.

Looks like a problem with C++ code generation for structs.
Certainly a bug that needs to be fixed.

I presume you mean "struct A" here?

Again, a problem in code generation of struct methods.

Please mark both JIRA issues as "Blocker". That would ensure that
they will not slip through the cracks and will be addressed asap.
Igor
P.S. Please let me know if you're unable to open JIRAs and I'll
open them for you.
