Bug ID: 60007
Summary: preprocessor aborts with internal error when
redefining a flag set by -D option
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: lutzwei at gmx dot de
Consider the following program stored in file "test.c" :
-------------------------
#define ANY_FLAG
int main() { int i=1;}
-------------------------
If you issue the command
cpp -DANY_FLAG test.c
you get an internal compiler error abort as follows:
----------------------------------------------------------------------
# 1 "test.c"
# 1 "<command-line>"
# 1 "test.c"
test.c:1:0: warning: "ANY_FLAG" redefined [enabled by default]
#define ANY_FLAG
^
<command-line>:0:0: note: this is the location of the previous definition
test.c:1:0: internal compiler error: Segmentation fault
#define ANY_FLAG
^
