--- Comment #10 from David Binderman <dcb314 at hotmail dot com> ---
This C code seems to fail with -O1:
int RB_Open_SingleDocumentation_document;
char RB_Open_SingleDocumentation_document_0,
RB_Open_SingleDocumentation_default_name;
char *RB_Open_SingleDocumentation_name;
void *calloc();
unsigned long strlen();
void RB_Open_SingleDocumentation() {
long size = 0;
if (RB_Open_SingleDocumentation_document)
size += strlen(&RB_Open_SingleDocumentation_document_0);
else
size += strlen(&RB_Open_SingleDocumentation_default_name);
RB_Open_SingleDocumentation_name = calloc(size);
}
cvise $ ~/gcc/results/bin/gcc -c -w -O1 bug1045.c
during GIMPLE pass: phiopt
bug1045.c: In function ‘RB_Open_SingleDocumentation’:
bug1045.c:14:1: internal compiler error: in factor_out_conditional_operation,
at tree-ssa-phiopt.cc:407

Might be useful as an additional test case.
