Bug ID: 28911
Summary: infcall.c:1287: internal-error:
call_function_by_hand_dummy: Assertion
`call_thread->thread_fsm () == sm' failed.
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: breakpoints
Assignee: unassigned at sourceware dot org
Reporter: ppluzhnikov at google dot com
Target Milestone: ---
This looks very similar to bug 23191, but has simpler test case.
Reproduced with GDB-10.0, 11.1, and current trunk
dc5483c989f29fc9c7934965071ae1bb80cff902.
// --- cut

void f2(const std::string& s) {}
void th() {
while (1) {
f2("a");
sleep(5);
}
}
void f(const std::string& s) {
f2(s);
}
int main(int argc,char* argv[]) {
std::thread t(th);
for (int i = 0; i < 10; i++) {
f(std::to_string(i));
}
t.join();
return 0;
}

Error in testing breakpoint condition:
The program stopped in another thread while making a function call from GDB.
Evaluation of the expression containing the function
(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char>
>::c_str() const) will be abandoned.
When the function is done executing, GDB will silently stop.

../../gdb/infcall.c:1287: internal-error: call_function_by_hand_dummy:
Assertion `call_thread->thread_fsm () == sm' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

This is being fixed in another bug, so picking that one
as canonical.
