 Hi Tom,

 No, it doesn't help. I tried changing RTLD_LAZY to RTLD_NOW in the dynamic 
 library loading code in boehm-gc. I also tried exporting LD_BIND_NOW=true and 
 that did not help.
 
 I then upgraded to glibc 2.1.2 from glibc 2.1.1 and that didn't help.
 
 The only way I can get things to work is to use -static with gcj and then 
 everything seems to work fine.  So whatever the gc is doing works well when 
 statically linked into the executable but dies when the gc code is loaded from a 
 shared library (or other shared libraries are loaded?).

 Where would I find the new GC code?  Would snapshots have it?  Is there a public 
 source tree?
 
 Thanks,
