Bug #: 51854
Summary: ICE in mangle.c with literal of complex floating type
Classification: Unclassified
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: hstong@ca.ibm.com
Host: powerpc64-unknown-linux-gnu
Target: powerpc64-unknown-linux-gnu
ICE with imaginary component in mangled expression.
## Small self-contained source (cmplxfMangle.cpp):
template <unsigned N> struct A;
template <typename U, typename V>
char foo(U, V);
template <typename U>
void bar(A<sizeof(foo(U(), 1.0fj))> *);
int main() {
bar<int>(0);
}
## Compiler invocation:
g++-4.6.0 cmplxfMangle.cpp -c
## Compiler output:
cmplxfMangle.cpp: In instantiation of âvoid bar(A<sizeof (char foo(U(),
(__complex__ float){0.0f, 1.0e+0f}))>*) [with U = int]â:
cmplxfMangle.cpp:10:15: instantiated from here
cmplxfMangle.cpp:7:6: internal compiler error: in write_template_arg_literal,
at cp/mangle.c:2772
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
## g++ -v output:

the C++ ABI
Confirmed.

ICE fixed for 4.6.3; mangling fixed for 4.7.0. I don't think this is worth
fixing in 4.4/4.5.
