Description rross 1999-08-12 02:10:17 UTC
When compiling a program with a 2 dimensional array, we get "segmentation fault" when executing the program when performing a string storage into a globally declared 2 dimentional array. This program compiles and executes properly on AIX, SCO Unixware, SCO Open Server, AT&T Unix V.4, and various releases of these systems. It also compiles and works correctly on Caldera Linux Release 1.2. I have a sample program that can be provided that exhibits the problem. We need to resolve this problem so that we can release our commercial software products (hopefully) on Redhat Linux 6.0. I can be contacted via e-mail at firstname.lastname@example.org. I hope to hear from you soon.

I cannot seem to be able to send a attachment to provide a sample of the code that exhibits the problem. If someone will e-mail me, I can reply with an attachment showing an example of the problem.

Just reply to this message with test program included. Thanks.

The declaration "char *Words" declares Words to be an array of pointers to char (note that it is not an array of arrays of char). Therefore the strings in the initializer " " are string constants (and thus readonly), not an initialized array of char (which would be read/write). If you want more explanation, go to comp.lang.c (or your favorite such source) - I realize that I'm not really offering a full explanation here. If you want to just get your code to work (without having to fix it), supply the -fwritable-strings option to gcc.
