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.

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 ++;
}
