gnat failure with profiledbootstrap

gnat failure with profiledbootstrap

[kevin diggs]

Hi,

Are there any known problems building gnat with a profiled build (for
4.3.5 - 3.4.6 seemed to work)? I get the following:

raised TYPES.UNRECOVERABLE_ERROR : comperr.adb:398

The languages selected was c, c++, and ada. An identical "bootstrap"
build seemed to work?

What will happen if I do a languages=ada? Does it still build the
languages needed to build ada? And what gets installed with make
install?

Thanks!
