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?
