The rpcrt4's server crosstest crashes on my WinXP and Win2k boxes (same seems
to happen on other systems according to test.winehq.org).

I have tried to find out the problem but this part of the code is really out of
my competence.

The problematic commit is a05923e1d303788c9b7bfda61eb2ca9ae48653f7

    rpcrt4: Add tests for varying and conformant varying arrays.

The conformance test crashes in NdrpEmbeddedRepeatPointerUnmarshall with an
access violation.

Stack trace is :
0022fa50 77e82a17 00249568 d6fb03f4 00000003
rpcrt4!NdrpEmbeddedRepeatPointerUnmarshall+0x9e
0022fa84 77e914ea 00000001 0022fcd4 00430652

0022fab8 0041a200 00000001 0022fc54 0000003c
rpcrt4!NdrVaryingArrayUnmarshall+0x177

NdrVaryingArrayUnmarshall is called from function get_5numbers() in server_c.c

Reverting the patch fix the problem.

CC'ed to Rob Shearman as it's his patch.

Hope this will help fixing the problem.

regards,
Nicolas Le Cam
