FC5t1's Eclipse crashes on start-up on x86-64 systems... https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=174612 ..due to this bug.. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13212 I don't believe this problem is unique to x86-64 - it's just highly reproducible on that platform. This is the same thing that was preventing RSSOwl from running on any platform. If we aren't prepared to import a new GC snapshot, or backport Hans' fix, then I propose we modify java-gcj-compat's java.c wrapper to LD_PRELOAD the following .so before every gij run. It makes sure that any stray pthread_create() calls go through the GC's thread registration process. Comments? /* pthread_create registration wrapper for libgcj.
