test case
I'm getting an internal compiler error both on gcc 4.7.0 on Ubuntu 12.04.1 and
an MinGW-w64 gcc 4.7.2 for Windows. A reduced source test case is attached. The
error does not occur as soon as I use the captured this pointer. Output is as
follows:
$ g++ -std=c++11 ice.cpp -o ice
ice.cpp: In lambda function:
ice.cpp:47:24: internal compiler error: Segmentation fault

My workaround was to define "auto self = this;" outside the lambda function, but using "this->" bypasses the issue as well. ^ permalink raw reply [flat|nested] 6+ messages in thread
