--- Comment #8 from Tijl Coosemans <t...@freebsd.org> --- (In reply to Shawn Webb from comment #7) Firefox is already compiled with -fPIE on FreeBSD and this works fine even with -Wl,-z,nocopyreloc and -fstack-protector-strong. The problem is only in the configure test for clock_gettime which is *not* compiled with -fPIE but *is* compiled with -Wl,-z,nocopyreloc and -fstack-protector-strong which enables stack protection in this test program while -fstack-protector is a no-op. Stack protection uses a variable named __stack_chk_guard which is defined in libc on FreeBSD. When compiled without -fPIE, variables in dynamic libraries accessed by the executable are copied to the executable's data segment so it can be accessed directly (without GOT lookup). This is called a copy-relocation, which is why compiling with -Wl,-z,nocopyreloc gives an error. So either Firefox should compile configure tests with -fPIE or FreeBSD should do what Linux does and make __stack_chk_guard a thread local variable (or both). -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
