libc++abi.dylib: terminating with uncaught exception of type std::length_error: vector

On macOS I’m attempt to uploadfs using PlatformIO. I run pio run -t uploadfs after creating the data directory (containing a JSON file) and after successfully uploading my program to a Wemos D1 Mini Pro board (ESP8266).

I an exception when I run this. From the verbose output I see pio running the below mkspiffs command.

"mkspiffs" -c data -p 256 -b 8192 -s -1069056 .pioenvs/d1_mini_pro/spiffs.bin
libc++abi.dylib: terminating with uncaught exception of type std::length_error: vector
*** [.pioenvs/d1_mini_pro/spiffs.bin] Error -6

Any idea what might be wrong or how to troubleshoot this? I’m using PlatformIO version 3.5.2rc4.

That is most likely caused by the fact that negative partition size (-s -1069056) is given. I think mkspiffs should check and give a better error message here, but you still need to find what calls mkspiffs and why the size is negative.

I've found a corresponding bug on platformio/platform-espressif8266 issue #69. It is said to be fixed in an upstream development branch (newer than current 1.6.0 release).

I was able to work around the problem by using a smaller than 16MB custom flash size by adding these builds flags in my platformio.ini file:

[env:d1_mini_pro]
build_flags = -Wl,-Teagle.flash.4m.ld

Do you want to keep this issue open for fixing the error message?
