Well, I fixed my problem. Don't know if it's related to yours or to the
Solaris problem, but it looks like the kind of thing that might be.
Fix: In models.wrm, change "Text" to "?Text" globally.
Diagnosis: Apparently Linux can't handle long lines (e.g. 200 characters) as
Text, only as ?Text.
Symptoms: xace exits with a segmentation fault when an object containing
a long Text line is picked, or when an attempt is made to delete the object,
or to load another object that links to it.
1. The problem does not occur on the Sparc (xace 1.91 and 1-10), or SGI or
DEC (xace 1.91; 1-10 not tested).
2. Freshly loaded objects usually can be manipulated without a problem. The
program must be exited and restarted before the failures start happening.
3. The smallest dataset that was demonstrated to fail was two objects, not
linked to each other.
Versions and configurations:
xace 1-9 or 1-10, CACHE1 800 to 10000, CACHE2 256 to 2000, DISK 10000 to 20000
Linux 0.99 patchlevel 13
8 MB RAM, 16 to 42 MB swap
machine Texas Instruments 486DX2/50 MHz
Dave, Ken, Jeff, thanks for your help in working on this.
