Hi all It has been four days that I try to port a C program that runs perfectly on SGI station (MIPS R12000 processor) to Linux (RH7.1 on dual PIII box). Since I failed to find the answer (to the question following) on the net, and before starting reading the code(about 900 lines), I decided to try this forum. If you think it's offtopic or annoying, please ingnore this message
Well, the problem is: I'm porting a program that runs perfecly on SGI station (R12000 processor). I've copied all the sources, headers, custom libraries (there were two of them) and the Makefile. There were some troubles with pointer initiations, but I managed to overcome them. In some point, when main() calls a function called search(...) which is in search.c file, the program crushes upon the first line. Electric Fence (with all possible options) did not found any problem before search() is called. It's worth to note that the entire program has only one malloc and no free(). Some more details: Compiler used on R1200: MIPSpro Compilers: Version 7.2.1 On linux : gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81) with -ggdb option and no optimization Here is the output of the core examination by gdb (the binary compiled by cc with -ggdb flag). ------------------------------------ Segmentation fault (core dumped) [bgbg:13:13:08 sc]$ gdb scwrl core GNU gdb 5.0rh-5 Red Hat Linux 7.1 Copyright 2001 Free Software Foundation, Inc.
