Måske lidt skrabet info:
debug_srcname (utils.c:3500): Del af claws-mail
unlink (utils.c:5023): Kald af systemets unlink fra ovenstående fil
g_unlink (gstdio.c:698): Kald af systemets unlink fra glib's portable
g_unlink (wrapper omkring systemets unlink)
unlink (utils.c:5050): Se ovenfor.

Nej, det er oversat og kører native.

Så derfor den glibc version, der findes på systemet.

Lidt info fra brugeren:

  I downloaded claws-mail-3.4.0cvs22 and compiled on FreeBSD
4.8-RELEASE. It makes clean and installs, but when I try to run it I
get a SIGBUS error. I have run it under DDD and this is the error I
get:

Program received signal SIGBUS, Bus error.
[Switching to process 32014, thread 0x82b0000]
0x081a79cf in unlink (filename=0x82b6f80 "/var/tmp/claws-mail-1000") at
utils.c:5046
^Z^Z/mnt4/mdh/claws-mail-3.4.0cvs22/src/common/utils.c:5046:109562:beg:0x81a79cf
(gdb)

  I tried getting a back trace, but it never ends and I have to kill
DDD. I am running claws-mail-3.4.0 right now and I not have any
problems.

--------
  I downloaded claws-mail-3.4.0cvs29, and I am still getting the SIGBUS
error. The output from --debug is the same. I did a bt and it still
just gives the following two line over and over:

#3804 0x081a7afd in unlink (filename=0x82b6f80
"/var/tmp/claws-mail-1000") at utils.c:5048 #3805 0x2894e3be in
g_unlink (filename=0x82b6f80 "/var/tmp/claws-mail-1000") at gstdio.c:741

---------
  I have been working on figuring this problem out, but I haven't come
up with anything. I added a debug_print statement in common/utils.c to
print the filename that it is trying to unlink. When I run the program
it prints:

utils.c:5023:filename = /var/tmp/claws-mail-1000

  It does this till it gets a Bus error. I'm not sure how many
hundreds of times it prints. Do you have any idea were it is coming up
with the filename?

  This is with version cvs46.
