How about we add code to automatically run gdb and collect a crash dump? We can't use MiniDumpWriteDump because gdb can't read Windows minidump files, and windbg can't understand DWARF symbols. Or actually, how about integrating Google's Breakpad? It doesn't require a local gdb, and it comes with a minidump-2-core utility that supposedly lets gdb debug the resulting dump files. --a2kfh3VBTjjWUuvDC5m4tmbxKPdO6vQnk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTL0s1AAoJEMAaIROpHW7I3w8QAMFSnZXLOtRuCN+r3oCAXhx5 b9vohero+IoJZtHG5agg4XfG7u2WHRCicw1eeSZhwhabJ1hKa6wF1VDi87IqH9N+ fIu8NU7FA9/i4YLm7t7Ai/baBNLBE3YSDyU8fhBMtdR1t6i7KEaZLaWt2mbYd0Vx JMuCNNh1QIDHR4KAsMUYSZPJ1G0XasfeXxOln+UAJYfyTt29cE4GD6JKSdncv+UD xP4q+28Oec5m+4nsaeqpjbE68Gp1oIWVG904ZaeRON/ra3OQtfHQE2tURfbIHGeh W5cwKvoFIaVeZjKneg6AfECMnlERa3Y2kMFA61X4Kzk04cBGGTxZ+cY+GO1vNoCu AoBL8G2AMMVsQrGe0pfnBfABeoM9p2ykj/E8AGm1OT6M9LoTJrToFEeaHPY+phun x2TBmgt7AAez5wNlgjJP3Yaedvq6IjGOV5bxQWSkHPrVetK71f2edrs5MSfeS95s 94l97qo7qvWvFay6sLaeruvxGmlkz0EOoQhS9dS605ereQgVssBce2R5gs6HtOJa 4v2G5HF/WjeuUAMWgryLraG12QbnPFHnA7s8eesbCWIroXgkR+mKQ6aYls5QLVyx qrofP9n8/7Z4scxIf/2BA5gtvsRLpt3VVzVimTGc0OIZGPOeVqIXeFOHWHiB58nB 1HOwO2SW75VKgPDhTAor =KwhQ -----END PGP SIGNATURE----- --a2kfh3VBTjjWUuvDC5m4tmbxKPdO6vQnk--
