I have had to drop back to build 2232 because of a serious problem with FBCMD.exe in 2380.
When logging Delpi compilations (XE2), in most (but not all) cases where a hint or warning is logged, I see a hundred or more lines containing just the source path, line number and 'warning:' before the actual warning line appears in full. Help&Manual builds are even worse: in this case the line "[info]" or somtimes "Preparing topics" appears continuously during the build, lines scrolling up the screen constantly. The build was running more slowly than usual until I stopped it.
Normally FBCMD builds scroll up the screen too fast to read, but with 2380 I noticed the changed patterm of long scrolling blocks of short lines.
I believe I saw this happening in a couple of earlier IDE builds of individual actions also, but I have now reverted because I had to get the build done.
