Wanted: buggy debug symbols I currently try to incorporate debug symbol tests into DStress. The test framework is quite simple: 1) compile and link the code 2) hand the executable and a gdb command sequence to GDB 3) search for a defined regular pattern in GDB's output A sample: ---source--- // @DSTRESS_DFLAGS@ -g void dummy(...){ } int main(){ int a=2; dummy(a); a=a/(a-2); /* line 9 */ dummy(a); return 0; } ---gdb-script--- run ---pattern--- sample\.d:9 If you can provide further test cases please post them to the digitalmars.D.bugs newsgroup or send them to dstress@kuehne.cn. Thanks, Thomas |

Posted in reply to Thomas Kühne | For that test, you may also want to add a pattern looking for your "line 9" comment, to make sure it actually breaks on that line, since gdb outputs the line. You're also missing the "b script.d:9" command in your gdb-script, to tell gdb to break.
This is a great idea. Will post more on the bugs NG.

There is no "break ..." required as line 9 is guaranteed to produce a Division-by-Zero exception.
