--- Comment #7 from ghjghj530-bubu at yahoo dot de ---
I tried debugging the GCC today (not my strong side).
I ended up to extracte the call to cc1plus.exe and started GDB with cc1plus.exe
as target.
If i just run the process the ICE still occurs with the same information as
before: "internal compiler error: in pp_format, at pretty-print.c:630"
So i set a breakpoint at this location and printed the backtrace and some
variables:
Breakpoint 2, pp_format (pp=pp@entry=0xbd9fba8, text=text@entry=0xbd9faec) at
../../gcc-6.3.0/gcc/pretty-print.c:630

Continuing at this position leads to the ICE
Does this help in any way? How can i contribute more information?
