What does gcc / strace say? That'd be more interesting in this case I think. Either that or higher trace level.

2003-02-12 19:52: Subject: Weird problem with Image.SVG in Pike 7.4/7.5
Hey all,
I'm having a problem with Image.SVG in that when trying to do indices(Image.SVG) then Pike hangs quite badly - the only way to stop it is to kill it. It happens only in the Debian packaged version for both Pike versions, the version compiled from the tarballs works fine. Until recently the Debian package was using the --traditional style of installation, but now it uses a modified --new-style one which in 90% resembles the default style with minor differences:
- all the pike code is installed in /usr/share/pike/X.Y.Z/
- all the binary files (.o, pike, .so) are in /usr/lib/pike/X.Y.Z/
- the files in /usr/share/pike/X.Y.Z/ are symlinked to from the /usr/lib/pike/X.Y.Z/ so that the layout looks like that:
$ pwd /usr/lib/pike/7.5.3/lib/modules ... lrwxrwxrwx 1 root root 59 2003-02-06 23:40 _Image_DWG.pmod -> ../../../../../share/pike/7.5.3/lib/modules/_Image_DWG.pmod -rw-r--r-- 1 root root 6062 2003-02-06 19:40 _Image_DWG.pmod.o -rw-r--r-- 1 root root 10908 2003-02-06 19:42 _Image_FreeType.so -rw-r--r-- 1 root root 39188 2003-02-06 19:42 _Image_GIF.so -rw-r--r-- 1 root root 32844 2003-02-06 19:42 _Image_JPEG.so drwxr-xr-x 2 root root 94 2003-02-06 23:40 _Image.pmod lrwxrwxrwx 1 root root 59 2003-02-06 23:40 _Image_PSD.pmod -> ../../../../../share/pike/7.5.3/lib/modules/_Image_PSD.pmod -rw-r--r-- 1 root root 20777 2003-02-06 19:40 _Image_PSD.pmod.o lrwxrwxrwx 1 root root 58 2003-02-06 23:40 _Image_PS.pmod -> ../../../../../share/pike/7.5.3/lib/modules/_Image_PS.pmod -rw-r--r-- 1 root root 8087 2003-02-06 19:40 _Image_PS.pmod.o -rw-r--r-- 1 root root 768976 2003-02-06 19:42 Image.so -rw-r--r-- 1 root root 8156 2003-02-06 19:42 _Image_SVG.so -rw-r--r-- 1 root root 2964 2003-02-06 19:42 _Image_TIFF.so -rw-r--r-- 1 root root 22540 2003-02-06 19:42 _Image_TTF.so lrwxrwxrwx 1 root root 59 2003-02-06 23:40 _Image_XCF.pmod -> ../../../../../share/pike/7.5.3/lib/modules/_Image_XCF.pmod -rw-r--r-- 1 root root 45024 2003-02-06 19:40 _Image_XCF.pmod.o -rw-r--r-- 1 root root 10756 2003-02-06 19:42 _Image_XFace.so lrwxrwxrwx 1 root root 59 2003-02-06 23:40 _Image_XPM.pmod -> ../../../../../share/pike/7.5.3/lib/modules/_Image_XPM.pmod -rw-r--r-- 1 root root 11477 2003-02-06 19:40 _Image_XPM.pmod.o lrwxrwxrwx 1 root root 53 2003-02-06 23:40 Java.pmod -> ../../../../../share/pike/7.5.3/lib/modules/Java.pmod -rw-r--r-- 1 root root 44761 2003-02-06 19:40 Java.pmod.o
so, as far as pike is concerned, the entire tree is in /usr/lib/pike/X.Y.Z/, the module/include paths are:
$ pike7.5 --show-paths master.pike...: /usr/lib/pike/7.5.3/lib/master.pike Module path...: /usr/local/share/pike7.5/site_pike /usr/local/share/pike/site_pike /usr/local/lib/pike7.5/site_pike /usr/local/lib/pike/site_pike /usr/lib/pike/7.5.3/lib/modules Include path..: /usr/local/include/pike7.5 /usr/local/include/pike /usr/lib/pike/7.5.3/lib/include Program path..:
$ pike7.4 --show-paths master.pike...: /usr/lib/pike/7.4.13/lib/master.pike Module path...: /usr/local/share/pike7.4/site_pike /usr/local/share/pike/site_pike /usr/local/lib/pike7.4/site_pike /usr/local/lib/pike/site_pike /usr/lib/pike/7.4.13/lib/modules Include path..: /usr/local/include/pike7.4 /usr/local/include/pike /usr/lib/pike/7.4.13/lib/include Program path..:
Running pike with -t gives the following result (output comes from pike 7.5):
- master.pike: 688: 8298f90->low_findprog("/usr/lib/pike/7.5.3/lib/modules/_Image_SVG",".so",0,1)
- master.pike: 516: 8298e58->lock(2)
- Return: module.c:67()->Builtin()->mutex_key()
- master.pike: 555: 8298f90->master_file_stat("/usr/lib/pike/7.5.3/lib/modules/_Image_SVG.so")
- master.pike: 295: 8298f90->combine_path_with_cwd("/usr/lib/pike/7.5.3/lib/modules/_Image_SVG.so")
- Return: "/usr/lib/pike/7.5.3/lib/modules/_Image_SVG.so"
- master.pike: 297: 8298f90->dirname("/usr/lib/pike/7.5.3/lib/modules/_Image_SVG.so")
- Return: "/usr/lib/pike/7.5.3/lib/modules"
- master.pike: 325: 82988b8->create()
- Return: Stat(-rw-r--r-- 8156b)
- master.pike: 555: 82988b8->[](1)
- Return: 8156
- master.pike: 560: 82988b8->[](3)
- Return: 1044556949
the above lines are the very last ones in the output - after that pike is hung.
Trying to call Image.SVG() renders the same effect - pike is hung. My next step will be to compile the .deb with full debugging info, but I thought that somebody might have a clue as to what's wrong.
TIA,
