We now understand why you did not see the crash with Ada, and eventually came
up with a tiny C++ testcase exhibiting the issue Richard Kenner raised.
Using the same compiler, could you please try to compile the reproducer below
with -fnon-call-exceptions:
// foo.cc
void hook (void)
{
}
void foo (void)
{
int x, y;
try {
y = 0;
} catch (...) {
hook ();
}
}
We are seeing this:
$ ./cc1plus -fnon-call-exceptions foo.cc
void hook()
void hook()
void foo()
void foo()
foo.cc:15: error: Call edges for non-call insn in bb 9
foo.cc:15: internal compiler error: verify_flow_info failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Thanks in advance,
Olivier
