ld: warning: unknown dwarf DW_FORM_strp (offset=0x41534800) is too big |
|||||
Issue descriptionBuilding Chrome with the Xcode 5.1.1 toolchain causes a huge number of ld warnings. This is particularly scary since official builds of Chrome still use the 5.1.1 toolchain. We should investigate this warning to see if there are any issues. I'm guessing that at worst, we might have some missing symbols. I don't know why these warnings don't show up in the logs: https://uberchromegw.corp.google.com/i/official.desktop/builders/mac64/builds/1112 I've tried this on two machines, with debug+component and release+non-component configurations. e.g. """ [1873/27054] LINK ./boringssl_spake25519_test ld: warning: unknown dwarf DW_FORM_strp (offset=0x41534800) is too big in obj/third_party/boringssl/boringssl_spake25519_test/malloc.o ld: warning: unknown dwarf DW_FORM_strp (offset=0x41534800) is too big in obj/third_party/boringssl/libboringssl.a(err_data.o) ld: warning: unknown dwarf DW_FORM_strp (offset=0x41534800) is too big in obj/third_party/boringssl/libboringssl.a(generic.o) ld: warning: unknown dwarf DW_FORM_strp (offset=0x41534800) is too big in obj/third_party/boringssl/libboringssl.a(cpu-aarch64-linux.o) ...

[mac triage] Sounds like a WontFix baed on #c1

I believe #c1 is saying that the word "unknown" is incorrect, but the rest of the message stands.

Right, I don’t agree that this is WontFix. If the string pointers are out of bounds (bad DWARF writing) or something just thinks that they are (bad DWARF reading), we may have a problem.

erikchen@ are you still seeing this?

We no longer build with xcode 5.1.1. I'll reopen if this is still an issue that I observe. |
