Have you filed a bug with Sun about this issue?
No, because the specific loop that failed hasn't been identified, so it's
difficult to give them a precise reproduction case.
Moreso, we need to patch this given the large number of Solaris cc compilers
deployed. Loop-data optimizations are a historical sore point with solaris
compilers, appearing to have many artificats from overly agressive optimization.
Research "-xdepend" bugs in the solaris CC release notes, any flavor from the
SunStudio 8 through 11.

One thing about -xdepend is that Solaris cc 5.x is unrolling one of our
loops incorrectly. If someone wants to simplify, try reducing the complex
for (;;) and while () loops to avoid (;;x++, y++) or (;x[c++] +=x;) sorts
of grammers which have apparently confounded the optimizer.

The fix is trivial; in the solaris-x86-cc line of Configure, you must
replace -fast -xO5 with -fast -xdepend=no (note: -xO5 was implied by
the -fast argument.) The implicit -xdepend=yes implied by -fast was
causing this failure.
There may be further code fixes in the evp code to ensure that data
dependencies in the loops can be unrolled and optimized.
excellent!
now it works fine
thanks a lot !
best regards,
