Hello Leif, I use valgrind stardard Debian sarge package, so there is no problem in installing it. I have no idea what this means. Maybe you could install the lastest one, svgalib-1.9.24. If you do, and if you do not remove the old /etc/vga/libvga.config you will have to edit the file manually to add a line NoHelper to avoid having to install svgalib_helper. I am going to try it now. What can I do to run Linrad under the debuggers? Hopefully someone else can answer this:-) No one answered that :-( 73, Ramiro. # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: svgalib segfaults
Hello again! I have just compiled svgalib 1.9.24 and linrad works great using NO_HELPER mode! No crashes, it works just fine. Can we conclude it was a svgalib bug? 73, Ramiro, EA1ABZ. # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

Hello Ramiro, I have just compiled svgalib 1.9.24 and linrad works great using NO_HELPER mode! No crashes, it works just fine. Can we conclude it was a svgalib bug? I think so. But one can never be 100% sure. There could be a bug in Linrad that 1.9.24 is not bothered about. On the other hand, 1.4.3 is old now and your laptop was probably not so old when 1.4.3 was finished so it might not be so well debugged for the new hardware. Another thing is that 1.9.24 could be very much faster and therefore a bug inside Linrad might not happen in the time window where it would bother svgalib. For the moment I will act as if I were 100% sure it was a svgalib bug:-) 73 Leif / SM5BSZ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

Fine Leif. I can reproduce the segfault every time try it. I think I could debug it fine because it crashes with consistence. I am at work know, I will try to do the debugging when I arrive at home and tell you the results. It is obvious that you have detected a bug. Maybe you can use a debugger to get some info about it? It could be an error in the Linrad code that might lead to various problems in the future so I am very interested to know. It could also be a bug inside svgalib or ALSA that cause an interrupt-related problem. Ok Leif, we will keep in touch! Ramiro.
