Bug ID: 44619
Summary: SEGV on erroneous input
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org
Reporter: jan.kratochvil at redhat.com

It prints an error but then it crashes.
I cannot provide a preprocessed source as -E does not produce anything.
If I remove compilation error the crash no longer happens.
Tested on updated Fedora 30 x86_64.
clang++ -c -o /dev/null -D'throw(...)=noexcept(false)'
/usr/include/glibmm-2.4/glibmm/variant.h -I/usr/include/glibmm-2.4 -isystem
/usr/include -std=c++17
clang-10: warning: treating 'c-header' input as 'c++-header' when in C++ mode,
this behavior is deprecated [-Wdeprecated]
/usr/include/glibmm-2.4/glibmm/variant.h:23:10: fatal error: 'glibmmconfig.h'
