Description
Any sketch using std::string
will either fail compiling or, if
void __throw_bad_alloc() {}
void __throw_bad_function_call() {}
void __throw_length_error(const char*) {}
};
gets removed from abi.cpp
, fails to run in dynamic mode.
Compiler output:
/ssd/Arduino15/packages/dev/tools/arm-zephyr-eabi/0.16.8/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld: /ssd/Arduino15/packages/dev/tools/arm-zephyr-eabi/0.16.8/bin/../lib/gcc/../../picolibc/arm-zephyr-eabi/lib/thumb/v8-m.main+fp/hard/libstdc++.a(functexcept.o): in function `std::__throw_bad_alloc()':
functexcept.cc:(.text.unlikely._ZSt17__throw_bad_allocv+0x0): multiple definition of `std::__throw_bad_alloc()';
Shell output on dynamic mode with overrides commented out
[00:00:00.204,000] <err> elf: sym 'memcpy': relocation out of range (0x2000cc76 -> 0x801b047)
Minimal reproducible example:
void setup() {
std::string c = "notworking";
Serial.println(c.c_str());
}
