I was afraid of that. This is part of a huge project, so I tried to extract what I could to make it fail without involving too much complexity. In particular, the actual code is using the Pari library.

Working on it. The pari_sp isn't actually doing anything at the moment (it was going to be a part of the garbage collection process) so I know that's not it.

cr_open

cr_open(3)						     Library Functions Manual							cr_open(3)

NAME

       cr_open() - open crash dump for reading

SYNOPSIS

DESCRIPTION

       The library call opens a crash dump and passes back a crash dump descriptor.

       The path argument points to a path name naming a crash dump directory or file, and must not exceed bytes in length.

       The CRASH * to which crash_cb points is set to a crash dump descriptor, which can then be passed to the other functions to access the crash
       dump.

       flags is a bitmask of zero or more of the following flag values, which affect the operation of future calls to libcrash routines  for  this
       crash dump, except for cr_verify(3), which has its own flags parameter.

       The library will not attempt to verify checksums of files in the crash
			     dump if this flag is set.

       The library will write messages to stderr during time-consuming operations
			     (decompressions and checksums) if this flag is set.

RETURN VALUE

       Returns zero for success.  Other possible return values are described in libcrash(5).

EXAMPLES

       The following call to opens crash dump contained in the directory and returns the crash dump descriptor For an example of reading the crash
       dump see the cr_read(3) manual entry.

AUTHOR

       was developed by HP.
