* [Bug c++/43875] New: gcc-4.5.0 - ICE on invalid lambda return @ 2010-04-23 22:48 paul dot bibbings at gmail dot com 2010-04-23 22:50 ` [Bug c++/43875] " pinskia at gcc dot gnu dot org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: paul dot bibbings at gmail dot com @ 2010-04-23 22:48 UTC (permalink / raw) To: gcc-bugs The following code causes an ICE in gcc-4.5.0. An error should be reported (as per n3092, 5.1.2/4) owing to the fact that the return statement is invalid - a brace-init-list is not an expression and hence the return type is void. 23:38:33 Paul Bibbings@JIJOU /cygdrive/d/CPPProjects/nano/gcc_bugs $cat _5_1_2_4.cpp int main() { auto x2 = []{ return { 1, 2 }; }; } 23:39:08 Paul Bibbings@JIJOU /cygdrive/d/CPPProjects/nano/gcc_bugs $i686-pc-cygwin-gcc-4.5.0 -Wall -save-temps -std=c++0x -c _5_1_2_4.cpp _5_1_2_4.cpp: In lambda function: _5_1_2_4.cpp:3:32: internal compiler error: in convert_like_real, at cp/call.c:4929 Please submit a full bug report, with preprocessed source if appropriate.
