Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: louis.granboulan.develo...@gmail.com
The bug is quite simple: when using -masm=intel and a global named "and", as

gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3
preprocessed file is
--- cut begin ---
# 1 "a.c"
# 1 "<interne>"
# 1 "<command-line>"
# 1 "a.c"
int and = 0;
int main()
{
return and;
}
--- cut end ---
