October 25, 2005 Bug in gdc or bug in dmd? | ||||
---|---|---|---|---|
| ||||
Here's the example program: ------------------------------------------------- const int *x; int y = 1; int main() { printf("*x is %d\n", *x); return 0; } static this() { x = &y; } ------------------------------------------------- dmd 0.136 compiles this without an error message, and of course the output is "*x is 1". The most recent version of gdc (0.15) issues this output when I try to compile the example program: ------------------------------------------------- const_lvalue.d:10: x is not an lvalue const_lvalue.d:0: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. ------------------------------------------------- Obviously gdc's internal compiler error is a bug in any case, but should it be possible to initialize 'const' variables in a module's static constructor? |

Posted in reply to Thomas Kuehne | In article <h3e833-a76.ln1@eiche.kuehne.cn>, Thomas Kuehne says... >David Rushby schrieb am 2005-10-25: >> Here's the example program: >> ... > >- -> http://digitalmars.com/d/attribute.html Thanks, Thomas. Somehow I missed the second part of the 'const' documentation when I looked at it previously. |
