Summary: ICE when goto into try/catch block
Product: D
Version: D1
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: ibuclaw ubuntu.com
The test case:
void main()
{
goto L1;
try { L1: { } }
catch { }
}
Results in an ICE when trying to compile.
Internal error: ../ztc/cgcod.c 989
Similarly, this produces bad codegen.
void main()
{
goto L1;
try { }
catch { L1: { } }
}
And a segmentation fault occurs during runtime. My guess is that because the
try{} body is empty, the entire block gets optimised out, but the goto
statement is still left in, where it now jumps to an invalid/null address.
