Summary: Function parameter and variable are allocated at the
same address
Product: gcc
Version: 3.3.2
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: sammy at ariana-dsl dot utu dot fi
CC: gcc-bugs at gcc dot gnu dot org
void append_exp(char *text) {
if (!text) return;
int orig_len = (v->expression) ? strlen(v->expression) : 0;
int dest_len = orig_len + strlen(text);
char *buf = NULL;
...
...
Parameter "text" and variable "buf" seems to be at the same (stack) address. So,
when buf is set to NULL the text also becomes NULL.
Target architecture is i386. Compiler parameters -g -O2 -Wall were used.
When compiling with gcc 3.2 the problem does not occur.
