Code for triggering the BUG: float nested_lambda() { float val;
[val]() { [val]() { } } } float nested_lambda() nested_lambda()::<lambda()> <stdin>:7:4: internal compiler error: Szegmens hiba Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. according to gdb, the segfault originates at: cp/semantics.c:2814, and it's a null pointer dereferencing. After a bit of inspection, it was revealed that in the code: decl = add_default_capture (lambda_stack, llambda_stack is NULL. I tried the code: float nested_lambda() { float val; [val]() { float val2 = val; [val2]() { } } } which seems to be working fine. -- Summary: [cxx0x-lambda] Segfault because of a nested lambda function Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: adam dot rak at streamnovation dot com GCC build triplet: x86_64-unknown-linux GCC host triplet: x86_64-unknown-linux GCC target triplet: x86_64-unknown-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41896
