Bug #: 11987
Summary: Should static variable roll back it's value when use
setjmp()/longjmp() with Clang -O option?
Product: clang
Version: 3.0
Platform: PC
OS/Version: FreeBSD
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs

Created attachment 8045
--> http://llvm.org/bugs/attachment.cgi?id=8045
compliled with "clang -O jmp_test.c"
jmp_test.c compiled with optimization option "clang -O jmp_test.c"
when run ./a.out, the output is:
-----------------------
in f1():
g, a, r, v, s
91, 92, 93, 94, 95
after long jump:
g, a, r, v, s
91, 2, 3, 94, 5
-----------------------
my question is:
should static variable such as "int static_val" roll back it's
value after longjmp()? it's value should be 95 or 5?
the code is attached below.
thank you.
