Hi , I will see the problem on WIN10 or WIN SERVER, the duplicate steps are as follows:
1. Write a simple code 'hello world' program and compiled the executable file using GCC. // hello.c #include <stdio.h> int main() { printf("Hello World\n"); return 0; } $ gcc hello.c -o hello.exe 2. Format the specified USB drive using command prompt. C:\> format <USB Drive Letter>: /fs:UDF /q 3. Put the executable files hello.exe and cygwin1.dll into the UDF format flash drive and execute. We will find that the execution error occurs with cygwin v3.2.x and above. F:\>hello.exe 0 [main] hello (16224) F:\hello.exe: *** fatal error - add_item ("\??", "/", ...) failed, errno 22 Stack trace: Frame Function Args 000FFFFCCE0 001800622EE (0018029F172, 0018027AE81, 00800000000, 000FFFF8B40) 000FFFFCCE0 0018004874A (00000000000, 000FFFFCCE0, 00180020010, 000FFFFABD6) 000FFFFCCE0 00180048782 (000FFFF9BD0, 00000000016, 00800000000, 00000000001) 000FFFFCCE0 001800E30BC (000FFFFCBD0, 000FFFFCDF0, 001800D7488, 00000000000) 000FFFFCCE0 00180133DC5 (001800D344A, 00000000000, 00000000000, 00000000000) 000FFFFCCE0 00180048DA5 (00000000000, 00000000000, 00000000000, 00000000000) 000FFFFFFF0 00180047856 (00000000000, 00000000000, 00000000000, 00000000000) 000FFFFFFF0 00180047904 (00000000000, 00000000000, 00000000000, 00000000000) End of stack trace This error does not occur in v3.1.7. Hope this will be resolved in the future.
