Bug ID: 78272
Summary: [7 Regression] ICE in unshare_expr_without_location
while building 471.omnetpp
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
Target Milestone: ---
I'm seeing a segfault in ipa-prop.c when building SPEC2006, omnetpp in
particular.
The reduced testcase is:
class A
{
public:
A ();
};
int a;
int
fn1 (double, int)
{
new A;
}
int
fn2 (int rng)
{
if (a)
return fn1 (2.0, rng);
}
int
fn3 (double rng)
{
fn2 (rng);
}
Compiling with -Ofast on aarch64-none-linux-gnu gives the ICE:
distrib.cpp:24:1: internal compiler error: Segmentation fault
}
