           Summary: Compile fail at "0x0E+" procedure
           Product: gcc
           Version: 3.4.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: yaxi1984@gmail.com


The gcc will always compile fail on below lines:

/// file: fail.c
int main(void)
{
    int a = 0x0E+0x0C;
    return 0;
}

But, after add an "SPACE" after 0x0E, it will compile pass.

/// file: pass.c
int main(void)
{
    int a = 0x0E +0x0C;
    return 0;
}


This is always fail on gcc 3.4.4, the latest version is not verified yet.
Here is my build details:
