Re: [Mingw-users] g++ string array in struct crash

[Greg J. <gv...@gm...>]

No need to justify -whatever- that should work, if it crashes a program ,,,
But this isn't the mailing list to report it to.   It probably has
little to do with mingw, anyway.
Maybe gcc itself has a bug which manifested only then; maybe the bug
is still there but
the particular compilation method goes around it.  You should document
this in bugzilla.
