#15520 closed defect (fixed)

tcl.dll causes startup crash

Reported by: polytekpatrick Owned by: datallah
Milestone: 2.10.8 Component: winpidgin (gtk)
Version: 2.10.7 Keywords: tcl, tcl.dll, crash
Cc: gbmr


I updated pidgin to 2.10.7 from 2.10.6 and found that it crashed immediately at startup. Same thing even after a fresh install with no plugins enabled. Deleting the file plugins/tcl.dll fixed the problem. My machine has ActiveTcl? installed (required by my work, so not something I can change). I figured out it was tcl.dll causing the crash by the pidgin.RPT and debug log (both attached).

  • Component changed from unclassified to winpidgin (gtk)
  • Owner changed from rekkanoryo to datallah

Looks like it's crashing in the stack-smashing protection code (which may mean that there's some sort of stack bug in the plugin initialization).

Sorry for bringing up old conversation, but this issue reproduced on my PC too. Currently I just removed tcl.dll file and pidgin works OK for me. But I can't understand, why it works fine in 2.10.6. There is same CALLBACK function call style but it don't crash. What was changed in 2.10.7 to make it crashing?

The change in 2.10.7 was to the version of gcc that's being used (which has a different default calling convention).
