It also fails using the Solaris implementation on sparc-sun-solaris2.9. It fails on i686-pc-cygwin, although actually most of the PCH tests fail on that platform. A failure in the PCH largefile test for a given platform means that PCH is unstable for that platform. A PCH will work for most source code files but will fail for large source code files. The user can not easily predict when a PCH will work and when it will fail. When a PCH fails, there is no easy way to compile the file without removing the PCH so that gcc does not find it. On i386-unknown-netbsdelf1.6.1, and probably other platforms, a direct consequence is that qt-x11-free-3.3.0 can not be built. Those sources test whether PCH works, and use it if they do. The test passes, but some of the source files are large. Those source files fail to build. -- Summary: PCH largefile test fails on various platforms Product: gcc Version: 3.5.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: pch AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ian at wasabisystems dot com CC: gcc-bugs at gcc dot gnu dot org GCC host triplet: i386-unknown-netbsdelf1.6.1 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14940
