When compiling Mozilla from CVS as of Nov 20 2002, the compilation fails on
mozilla/security/nss/lib/pkcs12/p12e.c if one uses optimization (tested with
-O and -O2):
pont@machia:/space/1/moz/mozilla/security/nss/lib/pkcs12$ gcc -save-temps -o Linux2.4_x86_glibc_PTH_OPT.OBJ/p12e.o -c -O2 -fPIC -DLINUX1_2 -Di386 -D_XOPEN_SOURCE -DLINUX2_1 -ansi -Wall -DLINUX -Dlinux -D_POSIX_SOURCE -D_BSD_SOURCE -DHAVE_STRERROR -DXP_UNIX -UDEBUG -DNDEBUG -D_REENTRANT -I/space/1/moz/mozilla/dist/include -I../../../../dist/public/nss -I../../../../dist/private/nss -I../../../../dist/include -I/space/1/moz/mozilla/dist/include/nspr -I/space/1/moz/mozilla/dist/include/dbm -I../../../../dist/public/dbm p12e.c
p12e.c: In function `sec_PKCS12CreateSafeBag':

Without optimization however, it works perfectly:
pont@machia:/space/1/moz/mozilla/security/nss/lib/pkcs12$ gcc -save-temps -o Linux2.4_x86_glibc_PTH_OPT.OBJ/p12e.o -c -fPIC -DLINUX1_2 -Di386 -D_XOPEN_SOURCE -DLINUX2_1 -ansi -Wall -DLINUX -Dlinux -D_POSIX_SOURCE -D_BSD_SOURCE -DHAVE_STRERROR -DXP_UNIX -UDEBUG -DNDEBUG -D_REENTRANT -I/space/1/moz/mozilla/dist/include -I../../../../dist/public/nss -I../../../../dist/private/nss -I../../../../dist/include -I/space/1/moz/mozilla/dist/include/nspr -I/space/1/moz/mozilla/dist/include/dbm -I../../../../dist/public/dbm p12e.c
