           Summary: dmd segmentation fault with large char[] template value
           Product: D
           Version: 1.00
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: kamm@incasoftware.de

void bug(char[] string)()

void main()

// I think the argument has 452 characters..

compiles. Add one more character to the template value argument, and the linker
returns the error
bug.d:(.gnu.linkonce.t_Dmain+0x4): undefined reference to
`_D3bug925__T3bugVG453aa453_31323637383930313 ...snip...

Add another character and dmd crashes with:
semantic3 bug
code      bug
function  main
function  bug
Segmentation fault

This actually came up in practice when using BCS' template parser generator, which takes the gammar as a template value parameter. Complex grammars will easily exceed the 452 character limitation.

You can sidestep the issue to some extent, I have updated the parser generator to do this. It basicly only uses the huge parameter in the mixin its self not the underlying template.


BTW I'm glad to see that dparse is being used, and would be interested in hearing about it.
