Hi all,

when my app try to load the dblib dll i get a segmentation fault. Previously the app worked like a charm. The only change is the recompilation of fpc. I downloaded the dblib.dll from ftp contrib and tried to used it but no luck.

"...

FPC version: 2.6.1
FPC svn revision: 22614

Lazarus svn revision: 39044

GDB version: 7.2

Any hint ?

What version of FPC were you previously using?

The previous version was a 2.6.1, 8 or 10 days old, don't remember exactly.

Hi again,

i can;t find a solution.

Deleted everything. Checked out fpc fixed fixes_2_6 branch and lazarus fixes_1_0 branch.

Compiler builded with the 2.6.0 stable and command line "make all install SVNVERSION="svnversion.exe" COPYTREE=echo UPXPROG=echo OPT="-gl -gw -godwarfsets -gt -Xs -Xg" INSTALL_PREFIX=%FPCDIR%\%FPCVERSION%" . Checked that the binutils are from
"fpcbuild/tags/release_2_6_0/install/binw32".
Checked that the make util has version <= 0.81. Ok. Lazarus builded using the newlly created fpc 2.6.1. The dblib.dll is from the contrib ftp place ( redownloaded just to be sure ).

Nothing ... The same seg fault. It crashes at a dbinit call in mssqlconn unit.

Plz, can someone look at it ?

well now my app is working again.

I didn't find the reason why. The solution was to delete the lazarus lpi and lpr and recreate them. Wasn't fpc fault.
