Hi All,
(MacOS X 10.4.6 on Mac Intel Core Duo).
I've experienced "EXC_BAD_INSTRUCTION" exception calling
CFPreferencesCopyValue(...) API function.
Having traced this call I detected that the exception is raised by the
following instruction:
.....
0x90824daa movdqa [ebp - 0x28], xmm0 (within
_CFReadBytesFromFile internal procedure)
.....
in
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundatio
n shared library (@0x90801000).
Here effective address of [ebp - 0x28] is not 16-aligned as required for
SSE2 "movdqa" instruction.
Also I should say that this exception doesn't occur every time I call
CFPreferencesCopyValue(...).
Really, in all cases when ebp = 0xXXXXXXX8, it's clear, this exception
doesn't occur.
Has anyone experienced the same problem? How to aviod that?
Thanks,
Alexander Klyuev, email@hidden
