Yes, in fact it was during the last week when we have found out (with
help of BinGOs and Ranguard via IRC) that gcc-4.4.7 and 4.6.1 (not only
with mingw-w64 runtime but also with mingw.org's runtime) produce perl
binaries that crash on Windows XP.
For strawberry perl 5.14.2.0 we have decided to use:
- on 32 bit version gcc-4.4.3 (with slightly old mingw-w64 runtime)

- on 64 bit version gcc-4.4.7(prereleae) (with mingw-w64 runtime 1.0.1)

Many thanks , this is a valuable piece of information for me as I was in
doubts where to start reporting/discussing the issue, now it is clear.

Why not. As for my opinion concerning gcc toolchain included in
strawberry perl:
- we would strongly prefer to use mingw-w64 (not mingw.org) runtime for
both 32/64bit
- we have no special preference as for the gcc version (but versions
like gcc-X.Y.0 are perhaps too "in development" for us)
- we need gcc toolchain supporting <gccroot>/include and <gccroot>/lib
directories in search paths (without explicit -I or -L options)
- we would appreciate gcc toolchain with frotran (maybe a kind of addon
or extra package) as it comes handy to PDL guys using strawberry

OK, I take it as your "gcc upgrade" request - we will probably aim at
gcc-4.6.2 + mingw-w64 runtime (v2 or latest v2RC)
However, currently the release candidates for strawberry 5.14.2.0 are
IMHO too good to let them fall on the floor. I think that the updated
gcc-toolchain cannot be expected sonner than in 5.14.2.1 (don't ask me
when as our release schedule is slightly demolished - as you have
probably noticed)
BTW for all that might be interested - latest RC's are available at:
