Building WebKit natives with debug symbols on 32 bit Linux

I'm new to this list and I have searched the archives, but haven't found 
a discussion about this. If I have missed it, please just direct me to 
the archived thread.

I'm trying to debug a crash in a native part of WebKit-JavaFX bindings 
( I have only been able 
to reproduce it on 32 bit platforms (Windows and Linux so far). I'm 
trying to build the WebKit natives with debugging symbols, so that I can 
pin-point the location of the crash in code using gdb. I have managed to 
do this successfully on 64 bit Linux, producing 1.7 GB large But on 32 bit Linux, where only I can reproduce the 
crash, the build fails with linker error: "memory exhausted" when trying 
to assemble the from object files. So far I have not 
been successful in my attempts to circumvent this build error. I fave 
tried the following:

- added '--no-keep-memory' to linker options. The man page says about it:
            ld normally optimizes for speed over memory usage by caching 
the symbol tables of input files in memory.  This option tells ld to 
instead optimize for memory usage, by
            rereading the symbol tables as necessary.  This may be 
required if ld runs out of memory space while linking a large executable.

- booted the 64bit Ubuntu system and chrooted into a 32 bit environment. 
Some say that with 64 bit kernel, each 32 bit user-space process has 
more address space than with 32 bit kernel.

- both of the above

My question to the list is: How do you guys produce 32 bit with debugging symbols? Have you been able to? Do you 
have any special tricks in your sleeves?
