Make fails near the end of a three stage build with an internal compiler error.

There were a lot of check errors. The results for Cygwin's "make -i check" are not available since I cannot complete the make (yet). The result of the tests for Linux are here: http://gcc.gnu.org/ml/gcc-testresults/2007-04/msg01490.html . The ./configure options and some notes about the libstdc++-v3 "make check" results are in the file.

In addition, there is a spelling mistake in that file, look for this sentance: // reasons (not, e.g., if memory is unabvailable, in which case The _actual_ location of the error is not in "exception.hpp" but in the code that compiles it. The test results for "C" show quite a few more errors than usual. The "G++" test results (for _Linux_, and NOT _Cygwin_) show only ONE error). If I could compile the compiler I could run the tests to try to find where the error is :) . If I can not figure out which portion of GCC compiles the file that causes the seg fault to occur. I will try to cheat and use different ./configure options to avoid that portion of the code (so I can run "make -i check" and post a report - that _might_ not help with this bug, since an option will be altered). -- Summary: Build fails with "exception.hpp:84: internal compiler error: Segmentation fault" Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: rob1weld at aol dot com GCC build triplet: i686-pc-cygwin GCC host triplet: i686-pc-cygwin GCC target triplet: i686-pc-cygwin http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31761
