Hi,
I found that OmniOrb 4.0.7 stable crashes when compiled with Visual
studio 2005 (vs8) static runtime (/MT) under certain circumstances.
The problem manifested for me when resolving NameService (testcase
source code attached) with a crash in release mode that disappears when
compiling for debug, or even with debug information. The problem
occurred when both OmniOrb libraries and the program were compiled with
/MT runtime, and disappeared sporadically.
I've tracked the cause to be the linker option "/OPT:REF" which gets
enabled by default for release builds, and disabled in debug. It enabled
"identical COMDAT folding", which to my understanding removes identical
functions and keeps just one. This causes a crash because it folds some
things it shouldn't, as you can see from the attached verbose linker
output snippet. It replaces the omniIdentity classes (Local,Remote,..)
thisClassCompare with a single copy, and because the classes are
identified by the function pointer (if I understood correctly), all
comparisons become true.
This causes the crash in my scenario in createObjRef (omniInternal.cc),
as you can see from the attached stacktrace (minimal) and program
outputs. It falsely identifies remoteIdentities as local and promptly
crashes.
As a workaround, you can build projects with static runtime that link
OmniOrb libraries with /OPT:NOICF , which disables the duplicate removal
and makes the code work. However, I think it would be beneficial in the
long run to change this code so it compiles correctly with /OPT:ICF
which is a default for new projects in VS2005.
Although I detected this in 4.0.7 and haven't tried newer versions, I
believe omniORB-4.1.0-beta2 to be affected as well because the relevant
sections of code seem similar.
I would be most interested in any thoughts, and ideas for a patch.
Best regards,
