Bug ID: 44920
Summary: [WebAssembly] Crash when building bullet with DWARF
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: WebAssembly
Assignee: unassignedbugs at nondot.org
Reporter: alonzakai at gmail.com
CC: llvm-bugs at lists.llvm.org
I tried to reduce this to a single file, but it's sensitive to that somehow -
apologies for not having a smaller testcase.
STR:
1. Get emscripten, https://github.com/emscripten-core/emscripten
2. In the root dir of emscripten, run
clang -target wasm32-unknown-emscripten -D__EMSCRIPTEN_major__=1
-D__EMSCRIPTEN_minor__=39 -D__EMSCRIPTEN_tiny__=8 -D_LIBCPP_ABI_VERSION=2
-Dunix -D__unix -D__unix__ -Werror=implicit-function-declaration -Xclang
-nostdsysteminc -Xclang -isystem`pwd`/system/include/libcxx -Xclang
-isystem`pwd`/system/lib/libcxxabi/include -Xclang
-isystem`pwd`/system/include/compat -Xclang -isystem`pwd`/system/include
-Xclang -isystem`pwd`/system/include/libc -Xclang
-isystem`pwd`/system/lib/libc/musl/arch/emscripten -Xclang
-isystem`pwd`/system/local/include -DHAVE_CONFIG_H -I. -I.. -O2 -Werror -O3
-Wno-dynamic-class-memaccess -Wno-format -Wno-format-extra-args
-Wno-format-security -Wno-pointer-bool-conversion -Wno-unused-volatile-lvalue

-Wno-pointer-bool-conversion -Wno-unused-volatile-lvalue
-Wno-c++11-compat-deprecated-writable-strings -Wno-invalid-pp-token
-Wno-shift-negative-value -std=c++03 -DEMSCRIPTEN
tests/bullet/src/BulletCollision/CollisionShapes/btCapsuleShape.cpp -Xclang
-isystem`pwd`/system/include/SDL -c -mllvm
-combiner-global-alias-analysis=false -mllvm -enable-emscripten-sjlj -mllvm
-disable-lsr -Itests/bullet/src -g
It will not crash without the -g at the end, but does crash with it:
1. <eof> parser at end of file
2. Code generation
3. Running pass 'Function Pass Manager' on module
'tests/bullet/src/BulletCollision/CollisionShapes/btCapsuleShape.cpp'.
4. Running pass 'WebAssembly Assembly Printer' on function
'@_ZNK14btCapsuleShape21calculateLocalInertiaEfR9btVector3'
