Would someone on the developers' team please comment on this problem:
In a nutshell, loading a GnuTLS DLL by a MinGW compiled Emacs causes
libintl DLL to be loaded, and if that libintl DLL in turns loads
libgcc_s_dw2-1.dll, the program crashes inside libgcc on exit, when
the runtime unloads all the DLLs loaded by Emacs. A related
discussion on the MinGW mailing list
Suggests that this is a general problem with DLLs linked against a
shared libgcc that uses dw2 unwinding.
Is there a bug in libgcc's dw2 unwinding code? Is it a fundamental
mistake to build DLLs that depend on libgcc as a shared library? Or
are the applications using libgcc_s_dw2-1.dll buggy and need to get
their act together in some way (if so, how)? Or anything else?
Thanks in advance.
