[Bug debug/12934] [3.4 regression] ICE with variable sized arrays in loc_descriptor_from_tree, at dwarf2out.c:8780

[reichelt at gcc dot gnu dot org]

The testcase can be reduced to

===========================================
inline int foo() { return 0; }

void bar()
{
    int buf[foo()];
}
===========================================

which fails on i686-pc-linux-gnu with "gcc -O -g":

bug.c: In function `bar':

bug.c:6: internal compiler error: in loc_descriptor_from_tree, at
dwarf2out.c:8780
Please submit a full bug report, [etc.]

The bug only affects mainline.

According to Phil's regression hunter it appeared between
2003-04-11-trunk (#264) and 2003-04-12-trunk (#265)
(although I had to specify -O2 for the search).
