saved eip question [was Re: c debugging w/ gdb revisited]

[jnf]

yea i didnt think so, but i figured id ask, i was trying to see if i could follow eip honestly.

any idea why a saved eip would be restored here

call function
add $0xsomevalue, %esp
push $value

why it would die in between add and push, why a saved eip would be restored @ that point is really my question, i guess im asking this to the wrong mailing list ;]
