246263 - reserve more space for executable when using prebinding

Status: RESOLVED FIXED

(SeaMonkey :: Build Config, defect)

Description

[Brian Ryner (not reading)]

For Firefox static builds, we need to move the base addresses of dependent
libraries up a bit or the executable runs into NSPR and the application does not
launch prebound.  The new addresses I'm using are still well within the
allowable range for application libraries (see
http://developer.apple.com/documentation/Performance/Conceptual/LaunchTime/Tasks/Prebinding.html)

I've seen this same problem on Mozilla suite builds (up to and including 1.7rc3):

/usr/libexec/fix_prebinding:
/usr/local/Applications/Mozilla.app/Contents/MacOS/libnspr4.dylib must be slid,
but fix_prebinding could not find a good place to relocate it.

Given the planned long lifetime of 1.7 and minimal exposure of this update (plus
the performance improvement), any chance of getting it into 1.7?
