Hello, again.

I re-built Crypto++ with the -O2 option added to CXXFLAGS. The build completed, but "cryptest.exe v" fails with a segmentation fault during the NR validation suite:

NR validation suite running...

passed    signature key validation
passed    signature and verification
passed    checking invalid signature
Generating new signature key...
Segmentation fault

(but the make file did warn me that -O2 might cause problems...)

I've seen that GCC 3.3.1 built, tested, and installed from the source distribution (make bootstrap etc.) compiles Crypto++ 5.1 (c5 module from the CVS this morning) with the default GNUmakefile.

However, the "release" build failed compiling cryptest.exe until I deleted the -ffunction-sections and -fdata-sections directives from the CXXFLAGS (see attached GNUmakefile).

Subsequently "cryptest.exe v" executed successfully, passing all tests. Has anybody else had this compile problem?
