[Bug middle-end/37236] internal compiler error: in mark_operand_necessary, at tree-ssa-dce.c:242

[dominiq at lps dot ens dot fr]

------- Comment #2 from dominiq at lps dot ens dot fr  2008-08-25 20:04 -------
Confirmed on i686-apple-darwin9. Works with 4.2.3, latest trunk (revision
139571) gives:

pr37236.f: In function 'fftrc':
pr37236.f:2: error: expected an SSA_NAME object
pr37236.f:2: error: in statement
# NMT.31 = VDEF <NMT.31> { NMT.31 }
IMAGPART_EXPR <(*x_29(D))[1]> = 0.0;
pr37236.f:2: internal compiler error: verify_ssa failed

Work around: replace X(1) by X(*).
