Maybe a debug files(s) is generated.
Let crash again and then look the bottom in the Windows Event Viewer. Do you see there files mentioned in the WER folder ?
In C:\ProgramData\Microsoft\Windows\WER ? And take the files with the time of the crash.
Can I download some where that ?
Maybe OneDrive or from your server. |

Yes, I'm sure. This is the procedure I followed:
- completely remove the Apache2 folder
- extract from the download from this site here (httpd-2.4.43-win64-VS16.zip)
- rename "conf" to "conf.org"
- create new "conf"
- xcopy all "conf" files from .41 to the new .43 "conf". Only files in "conf"!
- start Apache Monitor and then httpd with Apache Monitor
- call example 3-liner perl twice in browser
- 2x crash!
- stop server, exchange .43 mod_http2 with mod_http2_1874347.so and start server
- call example 3-liner perl in browser
- works!

The 2 crash files are here: Removed
I can offer to run httpd.exe again with GDB and with symbols. But I do not find symbols for .43. Can you point me to a symbols file for that version? |

Thanks !
Pity no debug file.
No other files in C:\ProgramData\Microsoft\Windows\WER ?
Also look in Control Panel\All Control Panel Items\Security and Maintenance\Problem Reports for files
Here are symbols:

Unfortunately this does not help as GDB cannot read Visual Studio symbol files:
| Code: | (gdb) symbol-file ../modules/mod_http2_src.pdb
`X:\Apps\Apache24\modules\mod_http2_src.pdb': can't read symbols: file format not recognized. |
Since I do not have Visual Studio installed, I cannot debug further... |

Yep for debug in Visual Studio the debug files in WER are needed for further debugging. You looked for files as mentioned in my post above ?
You tried ?
>gdb X:\Apps\Apache24\bin\httpd.exe
...
...
...
(gdb)run -X -e debug
...
...
(gdb)bt
same as without the symbols ? |

No, no further files in "C:\ProgramData\Microsoft\Windows\WER" as I linked already in the .zip file.
In "Problem Reports for files" there are entries for each crash. But not more information as from the Windows Event Viewer. I added one as an example:

gdb with "-e debug" is the same as without. It just prints in addition the list of loaded modules.
I created a dump using Sysinternal tool procdump:
| Code: | | procdump -64 -e -ma httpd.exe httpd.dmp |
May be this helps? Download the dump here: Removed
I tried to analyze it with kd. The result is here: Removed |
