C source code
The attached C code does this:
/home/dcb/gcc/results/bin/gcc -c -O1 -Wall -fexceptions bug843.c
during GIMPLE pass: uninit
src/eap-gtc.c: In function ‘eap_gtc_check_settings’:
src/eap-gtc.c:74:12: internal compiler error: in init_from_control_deps, at
gimple-predicate-analysis.cc:1740
0x1b161f5 predicate::init_from_control_deps(vec<edge_def*, va_heap, vl_ptr>
const*, unsigned int, bool)
../../trunk.git/gcc/gimple-predicate-analysis.cc:1740
0x1b16974 uninit_analysis::init_use_preds(predicate&, basic_block_def*,
basic_block_def*)
../../trunk.git/gcc/gimple-predicate-analysis.cc:1996
I will have a go at producing a git range and a reduction.
