After some exploration, I found the problem is because the APP_PLATFORM variable in Application.mk is set to a platform number which is no longer compatible with the Android NDK by the OSG CMake toolchain. This causes the Android to compile it using the most recent Android platform libraries which (for reasons I don't know) no longer provide functions which OSG relies (in particular rand and stat64).
This bug affects the current SVN repos for OSG 3.3.1, OSG 3.3.0, OSG 3.2.1 and OSG 3.2.0 (and possibly earlier).
I posted a longer discussion of what the problem is in this forum thread:
http://forum.openscenegraph.org/viewtopic.php?p=62012#62012
But essentially the fix is to change one line in OSG/PlatformSpecifics/Android/Application.mk.master.in from:
APP_PLATFORM := ${ANDROID_PLATFORM}
To
APP_PLATFORM := android-${ANDROID_PLATFORM}
The attached file will fix the bug in the 3.2.0 - 3.3.1 SVN repos for OSG.

The mac os sdk version is recognized by the current CMAKE script as 10.1 instead of 10.10 since it cuts the version string from the 4th place. I introduced a more reliable version checking based on splitting the returned version code into MAJOR MINOR and PATCH parts and reassemble the OSG sdk version afterwards.
I replaced the existing CMake code against the following (returning now version 10.10 as expected):
# Determine the canonical name of the selected Platform SDK
EXECUTE_PROCESS(COMMAND "/usr/bin/sw_vers" "-productVersion"
OUTPUT_VARIABLE OSG_OSX_SDK_NAME
OUTPUT_STRIP_TRAILING_WHITESPACE)
STRING(REPLACE "." ";" MACOS_VERSION_LIST ${OSG_OSX_SDK_NAME})
LIST(GET MACOS_VERSION_LIST 0 MACOS_VERSION_MAJOR)
LIST(GET MACOS_VERSION_LIST 1 MACOS_VERSION_MINOR)
LIST(GET MACOS_VERSION_LIST 2 MACOS_VERSION_PATCH)
SET(OSG_OSX_SDK_NAME "macosx${MACOS_VERSION_MAJOR}.${MACOS_VERSION_MINOR}")
Also i added the check for the new Version to some more find scripts.
Additionally the nil object in Objective C now seems to be equivalent with a null_ptr that cannot be passed as GLInt anymore. So i switched this in the PixelBufferCocoa.mm to pass a zero instead of nil.

The proxy node reader wrongly assumes options to be non NULL.

- the issue here is that the plugin is removing group nodes if
that group node only has one child. becuase transforms are also
group nodes, there were cases when the transform would have only
one child under it and would cause it to remove the translation
portion. this would cause all the vertex data to be loaded around
the last matrix operation, which in our case was the origin (0,0,0).
We work off of OSG 2.8.1 but see that this has not been addressed on latest yet. I’ve tested this against 2.8.1 and have cleanly applied it to my local repository off of latest."

It is caused by line 991 in RenderStage.cpp:
Code:
fbo_ext->glBlitFramebuffer(
0, 0, static_cast<GLint>(_viewport->width()), static_cast<GLint>(_viewport->height()),
0, 0, static_cast<GLint>(_viewport->width()), static_cast<GLint>(_viewport->height()),
blitMask, GL_NEAREST);
which is not taking into account the viewport x and y when performing the blit. It probably should be:
Code:
fbo_ext->glBlitFramebuffer(
static_cast<GLint>(_viewport->x()), static_cast<GLint>(_viewport->y()),
static_cast<GLint>(_viewport->width()) + static_cast<GLint>(_viewport->x()), static_cast<GLint>(_viewport->height()) + static_cast<GLint>(_viewport->y()),
static_cast<GLint>(_viewport->x()), static_cast<GLint>(_viewport->y()),
static_cast<GLint>(_viewport->width()) + static_cast<GLint>(_viewport->x()), static_cast<GLint>(_viewport->height()) + static_cast<GLint>(_viewport->y()),
blitMask, GL_NEAREST);

Note from Robert Osfield, made small tweak to above on merge, changing the width+x to x+width to make it read more naturally.

The issue with current code is that arrays are collected *before* duplicating shared arrays which leads to arrays that are correctly duplicated but that are not reordered.
Also the submitted patch contains a small cleaning in GeometryArrayGathrer as the _useDrawElements variable is not used; it is only set in the GeometryArrayGathrer constructor and VertexAccessOrderVisitor already checks that primitives have indexed type."

The crash disappears if I either (1) disable the use of images with stride
in the (public) osgGeo-library, or (2) add the following bugfix to Glyph.cpp.
This combination gives me the confidence that I understand where this problem
originates from, without trying to understand the full OpenGL details.
