Issue ID: 127252
Issue Type: DEFECT
Summary: All of AOO doesn't handle C++ exceptions properly,
making Clang unusable
Product: Build Tools
Version: 4.2.0-dev
Hardware: All
OS: Other OS
Status: CONFIRMED
Severity: Major
Priority: P5 (lowest)
Component: code
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
A lot of C++ code in AOO doesn't follow the C++ specifications when handling
exceptions, for example exceptions are thrown without being declared in the
function's prototype, which SHOULD result in a call to unexpected() and
termination of the application.
AOO however hides this fact using the -fno-enforce-eh-specs flag to GCC on
Linux (see main/solenv/gbuild/platform/linux.mk), and something similar on
Windows, so those platforms and compilers don't end up in unexpected() and
there is no crash. Clang, used on at least MacOS and FreeBSD, doesn't support
that flag, so they will crash in cases where Windows and Linux don't, making
those platforms DANGEROUSLY UNSTABLE!!!
See bug 125868 and its fix in commit 1765488 for a real world example. *Many*
more cases could exist!
Unless support can be added to Clang, a thorough audit of all code in AOO will
be needed to find and fix all the exception handling. Hopefully there's a way
to automate it somehow.
