Bug ID: 41279
Summary: Crash with SEH and -fprofile-generate
Product: new-bugs
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

Reproducer:
void f() {
__try { f(); }
__except (1) { return; }
__try { f(); }
__except (1) { }
}
clang-cl.exe -O2 -clang:-fprofile-generate -c test.cpp
Here's the stack though I'm not sure how much it helps, given the inlining in
my release build:
00 clang!`anonymous namespace'::PruneEH::runOnSCC
01 clang!`anonymous namespace'::CGPassManager::runOnModule
02 clang!llvm::legacy::PassManagerImpl::run
03 clang!clang::EmitBackendOutput
04 clang!clang::BackendConsumer::HandleTranslationUnit
05 clang!clang::ParseAST
I wonder if this is the PGO-analogue to the SEH gcov crash in bug 34833.
