Bug ID: 63818
Summary: unexpected/incorrect behavior
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: blaine at blainebell dot org

a simple program that shows a problem with the ++ operation
compile and run the program:
gcc test.c && ./a.out
outer a=3 b=3 c=3
then uncomment the second testouter() call, compile and rerun and get:
outer a=3 b=2 c=1
incr 4
outer a=6 b=5 c=4
notice the first line has not changed but has different behavior/outcomes
between the two runs.
