In general, when cc1 or cc1plus ICE-es, we try to reproduce the bug by running
compiler 3 times and comparing stderr and stdout on each attempt with
respective ones that were gotten as the result of previous compiler run (we
use temporary dump files to do this). If these files are identical, we add GCC
configuration (e.g. target, configure options and version), compiler command
line and preprocessed source code into last dump file, containing backtrace.
Following Jakub's approach, we trigger ICE_EXIT_CODE instead of
FATAL_EXIT_CODE in case of DK_FATAL error to differ ICEs from other fatal
errors, so try_generate_repro routine will be able to run even if fatal_error
occurred in compiler.
I still don't understand what's going on here with exit codes.
I'd second this, internal_error already exits with ICE_EXIT_CODE via
DK_ICE. Forcing fatal errors to return ICE_EXIT_CODE as well seems
unnecessary.
