While comparing list of exported symbols, libgcj_bc.so.1 hasn't dropped any symbols from 4.3 (correct, hasn't changed SONAME), but libgcj.so.10 dropped _Jv_CreateJavaVM and _Jv_GetStringChars symbols compared to libgcj.so.9. That wouldn't normally be an issue (they have different SONAME), but in this case, as they are listed in libgcj_bc.so and thus part of libgcj_bc.so.1 ABI, this is an ABI break. Seems _Jv_CreateJavaVM is still exported from libgcj.so.10, but unlike 4.3 as extern "C++" name (mangled, _Z16_Jv_CreateJavaVMP14_Jv_VMInitArgs), while previously it was exported as extern "C". _Jv_GetStringChars isn't exported at all.
Seen at least on x86_64-linux and i686-linux. Can this be fixed before 4.4 release? -- Summary: [4.4 Regression] libgcj.so dropped _Jv_CreateJavaVM and _Jv_GetStringChars symbols Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgcj AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38872
