Top Forums Programming C++ Segmentation error with bi-dimensional array Post 302624247 by nmset on Monday 16th of April 2012 04:31:24 AM

Code:
#include <math.c>
...
...
  const int nb = 30;
  wchar_t t[(int) pow(2, nb)][nb];

If class A is not instantiated, no seg fault occurs, up to nb = 30 (above is int upper limit), on both Fedora 16 and Debian squeeze.

If class A is instantiated, seg fault occurs with nb > 16, except nb = 30, on Fedora 16 (g++ (GCC) 4.6.3 20120306 (Red Hat 4.6.3-2) AND g++ (GCC) 4.6.2 20111027 (Red Hat 4.6.2-1)). On the Debian Squeeze host(g++ (Debian 4.4.5-8) 4.4.5), seg fault occurs with nb > 17.

Whether we need such huge arrays is not important, such behaviour is just erratic.

I'll just wait for next g++ bug fix release, it seems to be g++ version related.

Thanks.

SIZE(1) 						      General Commands Manual							   SIZE(1)

NAME
size - print the size of the sections in an object file SYNOPSIS
size [ option ... ] [ object ... ] DESCRIPTION
Size (without the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments. All other segments are totaled and that size is listed in the `others' column. The final two columns is the sum in decimal and hexadecimal. If no file is specified, a.out is used. The options to size(1) are: - Treat the remaining arguments as name of object files not options to size(1). -m Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of the segments in the file. -l When used with the -m option, also print the addresses and offsets of the sections and segments. -x When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal. -arch arch_type Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a universal file. (See arch(3) for the currently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display only the host architecture, if the file contains it; otherwise, all architectures in the file are shown. SEE ALSO
otool(1) BUGS
The size of common symbols can't be reflected in any of the numbers for relocatable object files. Apple Computer, Inc. July 28, 2005 SIZE(1)
