Ok, I now know what is going on.
First, the backtrace I submitted is wrong, the error happens in
free_pending_nulls in goption.c
On line 1034, the line
	*(n->ptr)[0] = '-';
tries to write into the string. However, n-ptr points to the read-only string
from context main, therefore a segfault happens. I think you were wrongly right
in closing the bug. Instead of assigning the string to myargv[1], a string has
to be malloc'd and copied.
Do you have a bugzilla account? I'm somehow reluctant to open one just for this one.
The link to the bug report is
https://bugzilla.mozilla.org/show_bug.cgi?id=273777

and a fix for this problem should be trivial.

greetings

Torsten
