Crash on exit VC8.0

[nobody]

Hi

I get a crash on exit of my application: when examining
the stack as show below I conclude that the crash
heppens in the cleanup of some static objects in the
boost::regex i.e. the destructor of
w32_regex_traits_implementation. This happens in
release build on VC8.0 with 1.33.1.
Was there a patch for this?

Thankx for feedback,

This works for me: I've just double checked by building and
running the regression test programs in release mode and
everything checks out OK.

So, can check that you don't have _DEBUG defined when
building with /MT or /MD (it'll cause you to link against
the wrong regex lib variant otherwise).  Then if you still
have a problem please provide more information:  

What runtime options are you using, /MT or /MD?
Are you using the static or dll regex version?

And if possible please provide a small VC++ project that
reproduces the issue.

Regards, John Maddock.

Hi John,

I have been testing all day, but can't seem to find out what
goes wrong:
all I know is that if I don't call any boost::regex function
everything goes all right
otherwise I get a crash while cleaning up the static
objects. I haven't changed the default settings so I guess
the dll loads statically. In debug every works fine. I guess
if I were overwriting memory in my own code that would fail
as well, but this is not entirely impossible of course. I
tried to enable BOOST_SP_ENABLE_DEBUG_HOOKS but I cannot
delete anything from the memory then...

These are the settings I use in VC8.0
compiler:
/Od /I "C:\Boost\include\boost-1_33_1" /D "WIN32" /D
"_DEBUG" /D "_WINDOWS" /D "TESTRELEASE" /D
"_VC80_UPGRADE=0x0710" /D "_AFXDLL" /D "_MBCS" /FD /EHsc
/RTC1 /MDd /Yu"stdafx.h" /Fp".\Debug/pWindows.pch"
/Fo".\Debug/" /Fd".\Debug/" /FR".\Debug\\" /W3 /nologo /c
/Zi /TP /errorReport:prompt

linker:
/OUT:".\Debug/pWindows.exe" /INCREMENTAL /NOLOGO /MANIFEST
/MANIFESTFILE:".\Debug\ProtoGMWindows.exe.intermediate.manifest"
/DEBUG /PDB:".\Debug/pWindows.pdb" /SUBSYSTEM:WINDOWS
/ERRORREPORT:PROMPT opengl32.lib glu32.lib glaux.lib gdiplus.lib

Thanks for your feedback!

The project settings you give there are for a debug build,
not a release build.  Can you try and reproduce the issue
with one of the sample regex programs and send me your IDE
project files if you get a test case?

Thanks, John.

After long investigation with the same problem (crash on program exit when actually using regex) I found that the problem is caused by mixing up the VC++ 2005 versions: the library was compiled with VC++ 2005 without SP1 and the program was compiled with VC++ 2005 with SP1. When I compiled the library with VC++ 2005 with SP1 the problem was gone.

[John Maddock]

Ahah! Yes mixing compiler versions would certainly do it, glad you got to the bottom of this!

John.

I encountered the exact same crashes and after some investigation I discovered that checked iterators were turned off in our project, but on (the default) for the regex library. I built the library again with _SECURE_SCL=0 and indeed, the crashes disappeared.
