Date: Tue, 05 Aug 2003 22:53:00 -0000 [thread overview] Message-ID: <20030805225315.11813.v.haisman@sh.cvut.cz> (raw) PLEASE REPLY TO gcc-bugzilla@gcc.gnu.org ONLY, *NOT* gcc-bugs@gcc.gnu.org. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11813 Summary: Make GCC not to assume that C functions can't throw. Product: gcc Version: 3.3.1 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: v dot haisman at sh dot cvut dot cz CC: gcc-bugs at gcc dot gnu dot org,v dot haisman at sh dot cvut dot cz GCC build triplet: *-*-* GCC host triplet: *-*-* GCC target triplet: *-*-* This test case shows that C++ exceptions are not caught across C function calls. Although this can be cured by supplying -fexceptions for compilation of C files, it is not always possible solution. For example when the program is linked with third party's binary C library whose compilation flags can't be controled. MSVC++ allows user to specify option /EHsc- that enables exceptions and also stops the compiler from assuming that C functions can't throw. I think that some users of GCC would like to have similar flag too.
