Try at least level -O2 and it will probably catch it. Without at least that level the compiler doesn't do enough work to detect out-of-bounds but it should still detect it at run-time.
Hi,
I turned on -O2 on linux fedora (g++ GCC 7.3.1 20180130 Red Hat 7.3.1-2) and also tried the same code on a FreeBSD unix (g++ FreeBSD Ports Collection 6.4.0) and they both didn't catch the array out-of-bounds when both -O2 and -Warray-bounds=2 are enabled.

Hi,
we are converting from IBM-AIX(xl c/c++ compiler) to Linux(GCC complier).
As a part of this i need to change the CFLAGS.
The xl c/c++ complier CFLAGS is

hi,
can we install gcc compiler in unix based OS(sun solar,IBM AIX,HP,etc) and also

It might be a simple one but I have this question bothering me for sometime.
When we do a symbol search inside the library directory (i.e. /usr/lib/*) via tools like nm; it takes a while to give us the results. However, its very quick when gcc is invoked to compile a program with the very same... (11 Replies)

icetboundingvertices
icetBoundingVertices(3) IceT Reference icetBoundingVertices(3)NAME
icetBoundingVertices -- set bounds of geometry.
Synopsis
#include <IceT.h>
void icetBoundingVertices( IceTInt size,
IceTEnum type,
IceTSizeType stride,
IceTSizeType count,
const IceTVoid * pointer );
Description
icetBoundingVertices is used to tell IceT what the bounds of the geometry drawn by the callback registered with icetDrawCallback or icetGL-
DrawCallback are. The bounds are assumed to be the convex hull of the vertices given. The user should take care to make sure that the drawn
geometry actually does fit within the convex hull, or the data may be culled in unexpected ways. IceT runs most efficiently when the bounds
given are tight (match the actual volume of the data well) and when the number of vertices given is minimal.
The size parameter specifies the number of coordinates given for each vertex. Coordinates are given in X-Y-Z-W order. Any Y or Z coordinate
not given (because size is less than 3) is assumed to be 0.0, and any W coordinate not given (because size is less than 4) is assumed to be
1.0.
The type parameter specifies in what data type the coordinates are given. Valid types are ICET_SHORT, ICET_INT, ICET_FLOAT, and ICET_DOU-
BLE, which correspond to types IceTShort, IceTInt, IceTFloat, and IceTDouble, respectively.
The stride parameter specifies the offset between consecutive vertices in bytes. If stride is 0, the array is assumed to be tightly packed.
The count parameter specifies the number of vertices to set.
The pointer parameter is an array of vertices with the first vertex starting at the first byte.
If data replication is being used, each process in a data replication group should register the same bounding vertices that encompass the
entire geometry. By default there is no data replication, so unless you call icetDataReplicationGroup, all process can have their own
bounds.
Errors
ICET_INVALID_ENUM
Raised if type is not one of ICET_SHORT, ICET_INT, ICET_FLOAT, or ICET_DOUBLE.
Warnings
None.
Bugs
None known.
