mozilla SIGSEGV

Post by Bill Caroselli » Mon Dec 22, 2003 4:10 am

This is, I believe, the very latest version of mozilla.
Here's the coreinfo.

I can reproduct this at will. If you need any additional info just ask.

BTW, The mozilla available at
http://www.qnxzone.com/~amardare/mozill ... public.qpr
does perform slightly better than the one at the online QNX respoitory.
It does not SIGSEGV under the same situation.

Looks like you've blown your stack. I think Adrian's given
the new version a bigger stack now.

Looks like you've blown your stack. I think Adrian's given
the new version a bigger stack now.
Two things I'd like to add:
1) The Online QNX repository seems to always be behind/difficult to update,
so rely on the www.qnxzone.com/~amardare/mozilla/...
location.
2) The problem you mentioned was fixed in code, not by increasing the stack
size.
Some problem later convinced me to increase the thread stack size to the
double of the regular amount - available in the next version.
