I'm seeing the following crash on -current: #0 0x2a31656b in thr_kill () at thr_kill.S:2 #1 0x2a2c5736 in pthread_kill () from /lib/libthr.so.3 #2 0x2a2c32c3 in raise () from /lib/libthr.so.3 #3 0x28237381 in XRE_InitEmbedding () from /usr/local/lib/firefox3/libxul.so #4 <signal handler called> #5 hash4 (keyarg=0xa8f497a, len=4294956678) at /usr/src/lib/libc/db/hash/hash_func.c:184 #6 0x2a39ab3d in __call_hash (hashp=0x8386800, k=0xa8f497a "S", len=-10618) at /usr/src/lib/libc/db/hash/hash.c:896 #7 0x2a3997fa in __split_page (hashp=0x8386800, obucket=7, nbucket=15) at /usr/src/lib/libc/db/hash/hash_page.c:356 #8 0x2a39ac09 in __expand_table (hashp=0x8386800) at /usr/src/lib/libc/db/hash/hash.c:865 #9 0x2a39922f in __addel (hashp=0x8386800, bufp=0x9d83ca0, key=0xbfbf8ac8, val=0xbfbf8ad0) at /usr/src/lib/libc/db/hash/hash_page.c:454 #10 0x2a39c2e0 in hash_access (hashp=0x8386800, action=HASH_PUT, key=0xbfbf8ac8, val=0xbfbf8ad0) at /usr/src/lib/libc/db/hash/hash.c:680 #11 0x2aa10b9c in ??

() from /usr/local/lib/firefox3/libnssdbm3.so This suggests that firefox3 is using the non-threadsafe db functions in libc. Is it possible to build firefox3 without them, or replace them with a newer version of Berkeley DB that is threadsafe? -- Jos Backus jos at catnook.com
