[Bug 44485] New: makes Delphi 7 debugger generate new exceptions by itself (regression)
https://bugs.winehq.org/show_bug.cgi?id=44485 Bug ID: 44485 Summary: makes Delphi 7 debugger generate new exceptions by itself (regression) Product: Wine Version: unspecified Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: development(a)winomega.com Distribution: --- Created attachment 60433 --> https://bugs.winehq.org/attachment.cgi?id=60433 WINEDEBUG=+seh Starting with commit a75e3f734d32bd98df9017f1a94819d2b6dca85d, the Delphi 7 debugger behaves erratically after catching an exception generated by the debugged program. It generates new floating point arithmetic exceptions, making debugging impossible and forces the debugger application to abort. The test program is a trivial application which raises an exception when clicking on a button. I'm attaching a WINEDEBUG=+seh log. Also, here's an annotated excerpt describing what I'm doing when each of the traces show up: I start the program and click on the button. Then get this: trace:seh:raise_exception code=eedfade flags=1 addr=0x7b43c5ac ip=7b43c5ac tid=0031 trace:seh:raise_exception info[0]=00450767 trace:seh:raise_exception info[1]=00473dbc trace:seh:raise_exception info[2]=004736c0 trace:seh:raise_exception info[3]=00426c58 trace:seh:raise_exception info[4]=0033ef44 trace:seh:raise_exception info[5]=0033ef08 trace:seh:raise_exception info[6]=0033edc4 trace:seh:raise_exception eax=7b428e39 ebx=00000018 ecx=0033ed30 edx=0033eda8 esi=0033ef08 edi=0033ef44 trace:seh:raise_exception ebp=0033ed88 esp=0033ed04 cs=0023 ds=13002b es=4d43002b fs=0063 gs=006b flags=00000212 I press F9 (run) to resume execution.

Process stopped. Use Step or Run to continue." I click OK. Debugger stops at vcl/Controls.pas class, at CallWindowProc; it appears as if the exception is triggered in CallWindowProc itself, but I can't tell for sure as the debugger environment is unreliable (if I were to single-step, it keeps triggering new exceptions).
