[bart dot vanassche at gmail dot com]

Output produced by the attached test program (as you can see, gcc doesn't warn
about initializing member variable m1 with the value of the uninitialized
member variable m2):

$ g++ -Wall -o uninitialized-member-variable uninitialized-member-variable.cpp
&& ./uninitialized-member-variable
a.m1 = 1629547062

$ gcc -v
