You are probably exceeding the limit of virtual memory. You must be keeping an array that grows without bounds.

If the files are really big, like > 2GB, consider asking the sysadmin to add more swap space. I personally believe that showing more of your code would help more than adding swap space. I think you are hogging memory in your code.

cscope-indexer(1)					      General Commands Manual						 cscope-indexer(1)

NAME
cscope-indexer - Script to index files for cscope SYNOPSIS
cscope-indexer [-v] [-f database_file] [-i list_file] [-l] [-r] DESCRIPTION
This script generates a list of files to index (cscope.out), which is then (optionally) used to generate a cscope database. You can use this script to just build a list of files, or it can be used to build a list and database. This script is not used to just build a data- base (skipping the list of files step), as this can be simply done by just calling "cscope -b". Normally, cscope will do its own indexing, but this script can be used to force indexing. This is useful if you need to recurse into sub- directories, or have many files to index (you can run this script from a cron job, during the night). It is especially useful for large projects, which can contstantly have source files added and deleted; by using this script, the changing sources files are automatically handled. Currently, any paths containing "/CVS/" or "/RCS/" are stripped out (ignored). OPTIONS
-f database_file Specifies the cscope database file (default: cscope.out). -i list_file Specifies the name of the file into which the list of files to index is placed (default: cscope.files). -l Suppress the generation/updating of the cscope database file. Only a list of files is generated. -r Recurse into subdirectories to locate files to index. Without this option, only the current directory is searched. -v Be verbose. Output simple progress messages. SEE ALSO
