Hi,

I run the following environment:

- Windows XP
- Eclipse Version: Indigo Service Release 1 Build id: 20110916-0149
- cygwin latest (downloaded 30.01.2012)
- gmock-1.6.0.zip

I first tried some toy application using the turtle example from the
forDummies document (see below).

Building works fine, but if I run the example I get an SIGSEV error in
the shell and when using Eclipse the following messages are shown in
the console:

13 [main] google_mock 3932 exception::handle: Exception:
STATUS_ACCESS_VIOLATION
1122 [main] google_mock 3932 open_stackdumpfile: Dumping stack
trace to google_mock.exe.stackdump

In gdb (no Eclipse), the following line is indicated as the source
line of the error:

Program received signal SIGSEGV, Segmentation fault.
0x00432af2 in join (ptr=0x611d7cd4, this=0x6fa6a4)
at ./gtest/include/gtest/internal/gtest-linked_ptr.h:113
113 while (p->next_ != ptr)

Could you have a look into this?

Can you reply with the contents of google_mock.exe.stackdump ?

Are you building gmock and gtest with the same options as your test?

They should all link to the same C++ run-time libraries.
gtest and gmock should be static libraries.
