I copied the file "gpsapp" to the location that was already there using derrick's version of the file, tagged it as executable, and here's what happens when I try to run it:

What have I done wrong?

The only time i had an issue with a program giving a memory error, genixia told me to...
[Startup]
reservecache=2
so... i guess... give that a try...

What have I done wrong?


Probably nothing. GPSapp has seg-faulted on you and dumped a stack trace.
It looks like somewhere along the way GPSapp has attempted to access memory that it doesn't own, and has been offically neutralised.
This sort of error is often caused by a bad or uninitialised pointer in the code.

It looks like I misapplied a patch. I checked the addresses against a non-stripped version of gpsapp and it pointed at the following bug.

          if (!strcmp(match, "routedir")) {

            int sz = (eof-(f+1)); /* reserve \0 */

            serport=(char *)malloc(sz);

            ^^^^^^^

            strncpy(routedir, (char *)f+1, sz); /* maybe no \0 */

            routedir[sz] = '\0'; 

Hmm, wonder how I managed to let that bad allocation slip through. New version will be out in about 5 minutes...

Cool, this time it's not my fault

It took a bit more than 5 minutes, because I managed to hose the anonymous CVS repository when I was rsyncing the updates to my desktop. However everything is back to normal now and the new version is available.

You da man!

0.16 works great, thanks!
