I just tried to compile the package htmldoc-1.8.27-174.19 with the GNU
C++ compiler version 4.5 snapshot 20100128 and the compiler said

image.cxx:389:1: error: definition in block 7 does not dominate use in block 13
for SSA_NAME: i_36 in statement:
# DEBUG i => i_36
image.cxx:389:1: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flags -g -O3 required.

This bug looks similar to 40711 and 42299, but it does seem to be
different to me.

------- Comment #4 from pinskia at gcc dot gnu dot org  2010-03-01 22:53 -------
Reduced testcase:
int gif_read_lzw(int input_code_size)
{
  int i, incode;
  static short fresh = 0,  code_size, set_code_size, clear_code,
table[2][4096], *sp;
  set_code_size = input_code_size;
  clear_code = 1 << set_code_size;
  for (i = 0; i < clear_code; i ++)
    table[1][i] = i;
  for (; i < 4096; i ++)
    code_size ++;
}
