At least I cannot reproduce the crash with the following skeleton:
You should look at the compile/link lines. First I would look at the
link lines:
This is the qmake one:
qcc -Vgcc_ntoarmv7le -lang-c++
-Wl,-rpath-link,/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/lib

-Wl,-rpath-link,/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib/qt4/lib
-o o.le-v7-g/WikiReader o.le-v7-g/.obj/main.o o.le-v7-g/.obj/wikimodel.o
o.le-v7-g/.obj/moc_wikimodel.o
-L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/lib
-L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib -L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib/qt4/lib
-L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6//usr/lib/qt4/lib -lbbcascades
-lQtDeclarative -lQtScript -lQtSvg -lQtSql -lsqlite3 -lz -lQtXmlPatterns
-lQtGui -lQtXml -lQtNetwork -lsocket -lQtCore -lm -lbps
This is the cmake one:
/opt/bbndk/host_10_0_9_404/linux/x86/usr/bin/ntoarmv7-c++ -Wall -fPIC
-Wall -fPIC -g3 -ggdb -O0 CMakeFiles/wikireader.dir/main.cpp.o

/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib/libQtDeclarative.so
-lbbcascades
-Wl,-rpath,/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib
Right off the bat they are using different compilers to link. I would
try to get the CMake one to match the qmake one by hand and see if you
can fix the problem. Once you figure out the magic command line that
makes it work, then we can figure out how to get CMake to produce the
same command line.
BTW, same thing with the compile lines. CMake does c++ and qmake does
gcc -lang-c++.
cat ../../cmake-test/main.cpp
int main() {return 0;}
cat ../../cmake-test/CMakeLists.txt
add_executable(cmake-test main.cpp)
I am running out of the quick ideas soon. Anything else to try?

Interesting finding! It happened to PySide as well on this platform
which may help with proceeding:

I have just tried to add the following libraries to the linkage
even if they seem unnecessary: -lz -lsocket -lm -lbps, but it is
still crashing. :'(
I have also tried to save out the wikireader.core file of mine,
and run through an arm gdb on the host, but it did not provide
too much information sadly even with a debug build:
(gdb) core wikireader.core
[New LWP 1]
Program terminated with signal 11, Segmentation fault.
#0 0x01d27380 in ?? ()
(gdb) thread apply all bt
Thread 1 (LWP 1):
#0 0x01d27380 in ?? ()
#1 0x00000000 in ?? ()
(gdb)
How can we proceed?
