Just to be safe, I did a find on my entire computer for "python2.0.dll". I only found one -- the one that is part of my test case. > Could you try "cygcheck -v ./main.exe" for both cases? Bad main.exe: $ cygcheck -v ./main.exe ./main.exe - os=4.0 img=1.0 sys=4.0 .\python2.0.dll - os=4.0 img=1.0 sys=4.0 "python2.0.dll" v0.0 ts=2000/10/26 4:52 C:\Cygwin\1.1.4\bin\cygwin1.dll - os=4.0 img=1.0 sys=4.0 "cygwin1.dll" v0.0 ts=2000/8/3 20:53 C:\WINNT\System32\KERNEL32.dll - os=4.0 img=4.0 sys=4.0 "KERNEL32.dll" v0.0 ts=1999/7/20 17:19 C:\WINNT\System32\ntdll.dll - os=4.0 img=4.0 sys=4.0 "ntdll.dll" v0.0 ts=1999/7/9 15:26 C:\WINNT\System32\KERNEL32.dll (already done) C:\Cygwin\1.1.4\bin\cygwin1.dll (already done) C:\WINNT\System32\KERNEL32.dll (already done) Good main.exe: $ cygcheck -v ./main.exe ./main.exe - os=4.0 img=1.0 sys=4.0 C:\Cygwin\1.1.4\bin\cygwin1.dll - os=4.0 img=1.0 sys=4.0 "cygwin1.dll" v0.0 ts=2000/8/3 20:53 C:\WINNT\System32\KERNEL32.dll - os=4.0 img=4.0 sys=4.0 "KERNEL32.dll" v0.0 ts=1999/7/20 17:19 C:\WINNT\System32\ntdll.dll - os=4.0 img=4.0 sys=4.0 "ntdll.dll" v0.0 ts=1999/7/9 15:26 C:\WINNT\System32\KERNEL32.dll (already done) .\python2.0.dll - os=4.0 img=1.0 sys=4.0 "python2.0.dll" v0.0 ts=2000/10/26 4:52 C:\Cygwin\1.1.4\bin\cygwin1.dll (already done) C:\WINNT\System32\KERNEL32.dll (already done) So the above shows a "difference" in the ordering of the DLLs in main.exe. I also noticed this difference when fiddling about with objdump -p: Bad main.exe: The Import Tables (interpreted .idata section contents) vma: Hint Time Forward DLL First Table Stamp Chain Name Thunk 00004000 00004054 00000000 00000000 00004150 00004090 DLL Name: python2.0.dll vma: Hint/Ord Member-Name 40c8 0 sub The Import Address Table is identical 00004014 00004060 00000000 00000000 0000417c 0000409c DLL Name: cygwin1.dll vma: Hint/Ord Member-Name 40d0 24 __main 40dc 540 calloc 40e8 594 cygwin_internal 40fc 611 dll_crt0__FP11per_process 4118 676 free 4120 812 malloc 412c 893 realloc The Import Address Table is identical 00004028 00004084 00000000 00000000 0000418c 000040c0 DLL Name: KERNEL32.dll vma: Hint/Ord Member-Name 4138 290 GetModuleHandleA The Import Address Table is identical Good main.exe: The Import Tables (interpreted .idata section contents) vma: Hint Time Forward DLL First Table Stamp Chain Name Thunk 00004000 00004054 00000000 00000000 00004168 00004090 DLL Name: cygwin1.dll vma: Hint/Ord Member-Name 40c8 24 __main 40d4 540 calloc 40e0 594 cygwin_internal 40f4 611 dll_crt0__FP11per_process 4110 676 free 4118 812 malloc 4124 893 realloc The Import Address Table is identical 00004014 00004078 00000000 00000000 00004178 000040b4 DLL Name: KERNEL32.dll vma: Hint/Ord Member-Name 4130 290 GetModuleHandleA The Import Address Table is identical 00004028 00004084 00000000 00000000 0000418c 000040c0 DLL Name: python2.0.dll vma: Hint/Ord Member-Name 4144 0 sub The Import Address Table is identical Does any of the above shed more light on the situation? Note that if I change the name to Python2.0.dll, python2.1.dll, python20.dll, or anything else that I can think of, main.exe run normally even though its DLL ordering is the same as python2.0.dll.
