I have a makefile based project that has "build result" field not set. I ran this binary in terminal. Then tried to attach to it; when attaching I selected the project binary belonged to. When Ilia tried this today evening, he's got "wrong argument" (or "incorrect argument") dialog. When I did this, no dialog appeared, but the debugger did not work properly. The gdb log showed that the IDE tried to pass the project directory as a path to symbol file: 10-file-symbol-file "/home/vk/testcode/misc/dlight.remote.impl/tools/fs_server" ... 10^error,msg="/home/vk/testcode/misc/dlight.remote.impl/tools/fs_server: Inappropriate ioctl for device."
If I select "no project" when attaching, I see no such effect.
