Hammer & Screwdriver Here is one approach

I had to 'fix' your input file; spacing and number of - characters. I figured you planned for the header line to be a regular format.

Code:
> cat file1
/*--- abcd_0050 ---*/
asdfjk
adsfkja
lkjljgafsd

/*--- abcd_0005 ---*/
lkjkljbfkgj
ldfksjgf
dfkgfjb

/*--- abcd_0055 ---*/
klhfdghd
dflkjgd
jfdg

> cat file1 | sed 's/\/\*/#\/\*/' | tr "\n" "~" | tr "#" "\n" | sort | tr -s "~" | tr "~" "\n"

/*--- abcd_0005 ---*/
lkjkljbfkgj
ldfksjgf
dfkgfjb

/*--- abcd_0050 ---*/
asdfjk
adsfkja
lkjljgafsd

/*--- abcd_0055 ---*/

cat(1)							      General Commands Manual							    cat(1)

Name
       cat - concatenate and print data

Syntax
       cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...

Description
       The  command reads each file in sequence and displays it on the standard output.  Therefore, to display the file on the standard output you
       type:
       cat file
       To concatenate two files and place the result on the third you type:
       cat file1 file2 > file3
       To concatenate two files and append them to a third you type:
       cat file1 file2 >> file3
       If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file.  Output is buffered in
       1024-byte blocks unless the standard output is a terminal, in which case it is line buffered.  The utility supports the processing of 8-bit
       characters.

Options
       -b   Ignores blank lines and precedes each output line with its line number.

       -e   Displays a dollar sign ($) at the end of each output line.

       -n   Precedes all output lines (including blank lines) with line numbers.

       -s   Squeezes adjacent blank lines from output and single spaces output.

       -t   Displays non-printing characters (including tabs) in output.  In addition to those representations used with the -v  option,  all  tab
	    characters are displayed as ^I.

       -u   Unbuffers output.

       -v   Displays  non-printing  characters (excluding tabs and newline) as the ^x.	If the character is in the range octal 0177 to octal 0241,
	    it is displayed as M-x. The delete character (octal 0177) displays as ^?.  For example, is displayed as ^X.
