<pre>I observed the issue while debugging something in the following code:
<a href="https://gitorious.org/xlr/xlr/commit/be2f08174b3a56a8673093f131945bb011350ddf">https://gitorious.org/xlr/xlr/commit/be2f08174b3a56a8673093f131945bb011350ddf</a>.
To reproduce easily, build XLR (I built it against LLVM 2.9, it's likely to
fail with more recent untested versions)
The following sequence exposes the problem:
ddd@Marypuce[atomic-gc] xlr> cat t.xl
writeln "real ", (10 ^ (2.0))
writeln "int ", (10 ^ 2)
ddd@Marypuce[atomic-gc] xlr> lldb xlr
Current executable set to 'xlr' (x86_64).
(lldb) b 'XL::OCompiledUnit::CallInteger2Real'
Breakpoint 1: where = xlr`XL::OCompiledUnit::CallInteger2Real(XL::Tree*,
XL::Tree*) + 29 at symbols.cpp:3550, address = 0x00000001000be95d
(lldb) r t.xl
Process 12381 launched: '/Users/ddd/Work/tao-master/tao/xlr/xlr/xlr' (x86_64)
Process 12381 stopped
* thread #1: tid = 0x16daa7, 0x00000001000be95d
xlr`XL::OCompiledUnit::CallInteger2Real(this=0x00007fff5fbfce40,
compiled=0x000000010103fb80, value=0x00000001010b6100) + 29 at
symbols.cpp:3550, queue = 'com.apple.main-thread, stop reason = breakpoint 1.1
frame #0: 0x00000001000be95d
xlr`XL::OCompiledUnit::CallInteger2Real(this=0x00007fff5fbfce40,
compiled=0x000000010103fb80, value=0x00000001010b6100) + 29 at symbols.cpp:3550
3547 // Compile code generating the children of an infix
3548 //
----------------------------------------------------------------------------
3549 {
-> 3550 Value *result = Known(value);
3551 result = code->CreateCall(compiler->xl_integer2real, result);
3552 NeedStorage(compiled);
3553 MarkComputed(compiled, result);
(lldb) p value
(XL::value_map) $0 = size=0 {}
The declaration of the function is:
Value *OCompiledUnit::CallInteger2Real(Tree *compiled, Tree *value)
So I expect 'value' to return a Tree *, not a value_map. The value_map is
declared in class OCompiledUnit.</pre>
