calling cygwin1.dll back
Mon Mar 29 11:47:00 GMT 1999
I've got a problem writing a dll, which is called from cygwin1.dll
and then calls it back. Say, test.exe calls cygwin1.dll, it calls
custom.dll, and then custom.dll tries to call memcpy from cygwin1.dll.
All 3 images has different "--image-base"s. I examine the code
and it appears that custom.dll correctly pushes all parameters onto
stack, then makes a does a "call" instruction and get to something like
1: x/i $eip 0x710079b4 <memcpy>: jmp *0x7100b104
As far, as i understand, it's a thunk. Alas, it's incorrectly
initialized -- 0x7100b104 contains 0xb124 instead of 0x6100b124.
