Bug ID: 79249
Summary: Lambda call does not create exception handler.
Product: gcc
Version: 6.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jesse at mind dot net
Target Milestone: ---
Created attachment 40593

Small program that triggers the bug.
When the attached program executes, a call to std::terminate() results rather
than the expected call to an exception handler.
Compile with:
g++-6 --std=c++14 -O0 -o ./minimal_break-gcc ./minimal_break.cpp
Expected output:
exception caught: std::exception
Observed output:
terminate called after throwing an instance of 'std::exception'
what(): std::exception
Aborted
Note:
Looking at the assembly output, it appears that code for checking exceptions is
not generated in main().
Compiler information:
Using built-in specs.
