clang 3.4 crashes while building libdwfl #18575
Comments
|
Hi Bero, Thanks for reporting this bug. Looks like it got lost during a recursive type emission. I can't reduce the test using CReduce, and from the stack trace is seems that it's lost while trying to find the Dwfl structure definition, which there isn't one. clang::CodeGen::CGDebugInfo::getOrCreateType(clang::QualType, llvm::DIFile) + 166 The function is: Dwfl * and the type is incomplete: typedef struct Dwfl Dwfl; Eric, any ideas? Regardless of this bug, Bero, I think you shouldn't compile with -g. Let's keep the debug issues for later and focus on the architecture problems. ;) |
|
It's possible that there was a messed up merge into 3.4. Eric and Manman, you asked me to merge some patches, but some of them didn't work. Can you look to see if things are okay there? |
|
This should not be related to the patches I asked you to pull to release 3.4. You pulled in two patches, and I pulled the rest :) Is this a regression from an earlier version of 3.4 branch? |
Ah! good. Thanks for pulling those in. :-) |
This is failing in 3.4 and ToT. I don't know if it's a regression from previous 3.4 release candidates... This seems pretty bad... |
|
Bero, Can you try a reproduce with the release candidate 1? http://llvm.org/pre-releases/3.4/rc1/ The x86 binaries should have all cross-compilation requirements already enabled. |
Extended Description
Compiling elfutils' libdwfl with clang (3.4 branch from a few days ago) results in:
