stl::unordered_map insert() causes abort() when out-of-memory #2827
Description
Hardware:
Board: ESP32 DoIt module - Chip is ESP32D0WDQ6 (revision 1)
Core Installation version: 1.0.2-rc1
IDE name: Arduino IDE 1.8.5
Flash Frequency: 80Mhz
PSRAM enabled: IDK
Upload Speed: 921600
Computer OS: Win 7
Description:
When I insert too much entries into unordered_map container, the ESP32 suddenly reboots. Should be throwing bad_alloc exception. I tried catching (...) also. Exception decoder can't decode anything. I am not sure if this is an ESP32/GCC/... problem.
The code:
std::unordered_map<int, std::string> l_map;
for(int i = 0; i < 100000; i++)
{
printf("%d\n", i);
try
{
auto l_result = l_map.insert({i, std::to_string(i)});
std::cout << l_result.second << std::endl;
}
catch(const std::bad_alloc&)
{
printf("OOOOOPS\n");
}
}
