Bug #: 56771
Summary: Integer Overflow? Building arm-rtems libgcc2
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: [email protected]
ReportedBy: [email protected]
This error occurs on some hosts. We suspect it occurs only on 32-bit hosts. It
appears that some magic is occurring where a constant is too large.
Host: CentOS 6.4 32-bit
Host GCC: 4.4.7 20120313 (Red Hat 4.4.7-3)
Target: arm-rtems4.11
Component Versions:
gcc-4.7.2
gmp-5.0.5
mpc-0.8.2
mpfr-3.0.1
newlib-2.0.0
