Description :
CONTEXT: This issue does not originate from an industrial application. It is reported for the lulz.
DESCRIPTION: The program below is accepted by gcc and clang, and rejected by Frama-C. It seems that the compilers are right to accept it.
~ $ cat t.c
unsigned f(void) { int a; static unsigned s = sizeof(a); return s; }
~ $ clang -std=c99 -pedantic -Wall -c t.c ~ $ frama-c t.c [kernel] preprocessing with "gcc -C -E -I. t.c" t.c:4:[kernel] user error: Forbidden access to local variable a in static initializer [kernel] user error: skipping file "t.c" that has errors. [kernel] Frama-C aborted: invalid user input. ~ $
